It may be used to configure projects in scripts. Project configuration settings may be specified on the command line with the -D option. The -i option will cause cmake to interactively prompt for such settings.</p> <p>CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.</p> <h2><a name="section_Options"></a>Options</h2> <ul> <li><a href="#opt:-Cinitial-cache"><b><code>-C <initial-cache></code></b></a></li> <li><a href="#opt:-Dvar:typevalue"><b><code>-D <var>:<type>=<value></code></b></a></li> <li><a href="#opt:-Uglobbing_expr"><b><code>-U <globbing_expr></code></b></a></li> <li><a href="#opt:-Ggenerator-name"><b><code>-G <generator-name></code></b></a></li> <li><a href="#opt:-Ttoolset-name"><b><code>-T <toolset-name></code></b></a></li> <li><a href="#opt:-Wno-dev"><b><code>-Wno-dev</code></b></a></li> <li><a href="#opt:-Wdev"><b><code>-Wdev</code></b></a></li> <li><a href="#opt:-E"><b><code>-E</code></b></a></li> <li><a href="#opt:-i"><b><code>-i</code></b></a></li> <li><a href="#opt:-LAH"><b><code>-L[A][H]</code></b></a></li> <li><a href="#opt:--builddir"><b><code>--build <dir></code></b></a></li> <li><a href="#opt:-N"><b><code>-N</code></b></a></li> <li><a href="#opt:-Pfile"><b><code>-P <file></code></b></a></li> <li><a href="#opt:--find-package"><b><code>--find-package</code></b></a></li> <li><a href="#opt:--graphvizfile"><b><code>--graphviz=[file]</code></b></a></li> <li><a href="#opt:--system-informationfile"><b><code>--system-information [file]</code></b></a></li> <li><a href="#opt:--debug-trycompile"><b><code>--debug-trycompile</code></b></a></li> <li><a href="#opt:--debug-output"><b><code>--debug-output</code></b></a></li> <li><a href="#opt:--trace"><b><code>--trace</code></b></a></li> <li><a href="#opt:--warn-uninitialized"><b><code>--warn-uninitialized</code></b></a></li> <li><a href="#opt:--warn-unused-vars"><b><code>--warn-unused-vars</code></b></a></li> <li><a href="#opt:--no-warn-unused-cli"><b><code>--no-warn-unused-cli</code></b></a></li> <li><a href="#opt:--check-system-vars"><b><code>--check-system-vars</code></b></a></li> <li><a href="#opt:--help-commandcmdfile"><b><code>--help-command cmd [file]</code></b></a></li> <li><a href="#opt:--help-command-listfile"><b><code>--help-command-list [file]</code></b></a></li> <li><a href="#opt:--help-commandsfile"><b><code>--help-commands [file]</code></b></a></li> <li><a href="#opt:--help-compatcommandsfile"><b><code>--help-compatcommands [file]</code></b></a></li> <li><a href="#opt:--help-modulemodulefile"><b><code>--help-module module [file]</code></b></a></li> <li><a href="#opt:--help-module-listfile"><b><code>--help-module-list [file]</code></b></a></li> <li><a href="#opt:--help-modulesfile"><b><code>--help-modules [file]</code></b></a></li> <li><a href="#opt:--help-custom-modulesfile"><b><code>--help-custom-modules [file]</code></b></a></li> <li><a href="#opt:--help-policycmpfile"><b><code>--help-policy cmp [file]</code></b></a></li> <li><a href="#opt:--help-policiesfile"><b><code>--help-policies [file]</code></b></a></li> <li><a href="#opt:--help-propertypropfile"><b><code>--help-property prop [file]</code></b></a></li> <li><a href="#opt:--help-property-listfile"><b><code>--help-property-list [file]</code></b></a></li> <li><a href="#opt:--help-propertiesfile"><b><code>--help-properties [file]</code></b></a></li> <li><a href="#opt:--help-variablevarfile"><b><code>--help-variable var [file]</code></b></a></li> <li><a href="#opt:--help-variable-listfile"><b><code>--help-variable-list [file]</code></b></a></li> <li><a href="#opt:--help-variablesfile"><b><code>--help-variables [file]</code></b></a></li> <li><a href="#opt:--copyrightfile"><b><code>--copyright [file]</code></b></a></li> <li><a href="#opt:--help-help-usage-h-H"><b><code>--help,-help,-usage,-h,-H,/?</code></b></a></li> <li><a href="#opt:--help-fullfile"><b><code>--help-full [file]</code></b></a></li> <li><a href="#opt:--help-htmlfile"><b><code>--help-html [file]</code></b></a></li> <li><a href="#opt:--help-manfile"><b><code>--help-man [file]</code></b></a></li> <li><a href="#opt:--version-versionVfile"><b><code>--version,-version,/V [file]</code></b></a></li> </ul> <ul> <li> <a name="opt:-Cinitial-cache"></a><b><code>-C <initial-cache></code></b>: Pre-load a script to populate the cache.<br /> <p>When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project. This option may be used to specify a file from which to load cache entries before the first pass through the project's cmake listfiles.

The answers are used to set cmake cache values.</p> </li> <li> <a name="opt:-LAH"></a><b><code>-L[A][H]</code></b>: List non-advanced cached variables.<br /> <p>List cache variables will run CMake and list all the variables from the CMake cache that are not marked as INTERNAL or ADVANCED. This will effectively display current CMake settings, which can then be changed with -D option. Changing some of the variables may result in more variables being created. If A is specified, then it will display also advanced variables. If H is specified, it will also display help for each variable.</p> </li> <li> <a name="opt:--builddir"></a><b><code>--build <dir></code></b>: Build a CMake-generated project binary tree.<br /> <p>This abstracts a native build tool's command-line interface with the following options:<br /></p> <pre> <dir> = Project binary directory to be built.<br /> --target <tgt> = Build <tgt> instead of default targets.<br /> --config <cfg> = For multi-configuration tools, choose <cfg>.<br /> --clean-first = Build target 'clean' first, then build.<br /> (To clean only, use --target 'clean'.)<br /> --use-stderr = Don't merge stdout/stderr output and pass the<br /> original stdout/stderr handles to the native<br /> tool so it can use the capabilities of the<br /> calling terminal (e.g. colored output).<br /> -- = Pass remaining options to the native tool.<br /></pre> <p>Run cmake --build with no options for quick help.</p> </li> <li> <a name="opt:-N"></a><b><code>-N</code></b>: View mode only.<br /> <p>Only load the cache.

The actual file name of the library built is constructed based on conventions of the native platform (such as lib<name>.a or <name>.lib).<br /></p> <p>STATIC, SHARED, or MODULE may be given to specify the type of library to be created. STATIC libraries are archives of object files for use when linking other targets. SHARED libraries are linked dynamically and loaded at runtime. MODULE libraries are plugins that are not linked into other targets but may be loaded dynamically at runtime using dlopen-like functionality. If no type is given explicitly the type is STATIC or SHARED based on whether the current value of the variable BUILD_SHARED_LIBS is true. For SHARED and MODULE libraries the POSITION_INDEPENDENT_CODE target property is set to TRUE automatically.<br /></p> <p>By default the library file will be created in the build tree directory corresponding to the source tree directory in which the command was invoked.

No rules are generated to build it. The target name has scope in the directory in which it is created and below, but the GLOBAL option extends visibility. It may be referenced like any target built within the project. IMPORTED libraries are useful for convenient reference from commands like target_link_libraries. Details about the imported library are specified by setting properties whose names begin in "IMPORTED_". The most important such property is IMPORTED_LOCATION (and its per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main library file on disk.

An object library compiles source files but does not archive or link their object files into a library. Instead other targets created by add_library or add_executable may reference the objects using an expression of the form $<TARGET_OBJECTS:objlib> as a source, where "objlib" is the object library name. For example:<br /></p> <pre> add_library(... $<TARGET_OBJECTS:objlib> ...)<br /> add_executable(... $<TARGET_OBJECTS:objlib> ...)<br /></pre> <p>will include objlib's object files in a library and an executable along with those compiled from their own sources. Object libraries may contain only sources (and headers) that compile to object files. They may contain custom commands generating such sources, but not PRE_BUILD, PRE_LINK, or POST_BUILD commands. Object libraries cannot be imported, exported, installed, or linked. Some native build systems may not like targets that have only object files, so consider adding at least one real source file to any target that references $<TARGET_OBJECTS:objlib>.<br /></p> <p>The signature<br /></p> <pre> add_library(<name> ALIAS <target>)<br /></pre> <p>creates an alias, such that <name> can be used to refer to <target> in subsequent commands.

The binary_dir specifies the directory in which to place the output files. If it is a relative path it will be evaluated with respect to the current output directory, but it may also be an absolute path. If binary_dir is not specified, the value of source_dir, before expanding any relative path, will be used (the typical usage). The CMakeLists.txt file in the specified source directory will be processed immediately by CMake before processing in the current input file continues beyond this command.<br /></p> <p>If the EXCLUDE_FROM_ALL argument is provided then targets in the subdirectory will not be included in the ALL target of the parent directory by default, and will be excluded from IDE project files. Users must explicitly build targets in the subdirectory. This is meant for use when the subdirectory contains a separate part of the project that is useful but not necessary, such as a set of examples. Typically the subdirectory should contain its own project() command invocation so that a full build system will be generated in the subdirectory (such as a VS IDE solution file).

The CMake Policy mechanism is designed to help keep existing projects building as new versions of CMake introduce changes in behavior. Each new policy (behavioral change) is given an identifier of the form "CMP<NNNN>" where "<NNNN>" is an integer index. Documentation associated with each policy describes the OLD and NEW behavior and the reason the policy was introduced. Projects may set each policy to select the desired behavior. When CMake needs to know which behavior to use it checks for a setting specified by the project. If no setting is available the OLD behavior is assumed and a warning is produced requesting that the policy be set.<br /></p> <p>The cmake_policy command is used to set policies to OLD or NEW behavior. While setting policies individually is supported, we encourage projects to set policies based on CMake versions.<br /></p> <pre> cmake_policy(VERSION major.minor[.patch[.tweak]])<br /></pre> <p>Specify that the current CMake list file is written for the given version of CMake. All policies introduced in the specified version or earlier will be set to use NEW behavior.

This effectively requests behavior preferred as of a given CMake version and tells newer CMake versions to warn about their new policies.

A new entry on the policy stack is managed automatically for each subdirectory to protect its parents and siblings. CMake also manages a new entry for scripts loaded by include() and find_package() commands except when invoked with the NO_POLICY_SCOPE option (see also policy CMP0011). The cmake_policy command provides an interface to manage custom entries on the policy stack:<br /></p> <pre> cmake_policy(PUSH)<br /> cmake_policy(POP)<br /></pre> <p>Each PUSH must have a matching POP to erase any changes.

If the argument HEX is given, the binary data will be converted to hexadecimal representation and this will be stored in the variable.<br /></p> <p>MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a cryptographic hash of the content of a file.<br /></p> <p>STRINGS will parse a list of ASCII strings from a file and store it in a variable. Binary data in the file are ignored. Carriage return (CR) characters are ignored. It works also for Intel Hex and Motorola S-record files, which are automatically converted to binary format when reading them. Disable this using NO_HEX_CONVERSION.<br /></p> <p>LIMIT_COUNT sets the maximum number of strings to return. LIMIT_INPUT sets the maximum number of bytes to read from the input file. LIMIT_OUTPUT sets the maximum number of bytes to store in the output variable. LENGTH_MINIMUM sets the minimum length of a string to return. Shorter strings are ignored. LENGTH_MAXIMUM sets the maximum length of a string to return. Longer strings are split into strings no longer than the maximum length.

Globbing expressions are similar to regular expressions, but much simpler. If RELATIVE flag is specified for an expression, the results will be returned as a relative path to the given path. (We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate.)<br /></p> <p>Examples of globbing expressions include:<br /></p> <pre> *.cxx - match all files with extension cxx<br /> *.vt? - match all files with extension vta,...,vtz<br /> f[3-5].txt - match files f3.txt, f4.txt, f5.txt<br /></pre> <p>GLOB_RECURSE will generate a list similar to the regular GLOB, except it will traverse all the subdirectories of the matched directory and match the files.

If LOG var is specified a log of the download will be put in var. If STATUS var is specified the status of the operation will be put in var. The status is returned in a list of length 2. The first element is the numeric return value for the operation, and the second element is a string value for the error. A 0 numeric error means no error in the operation. If TIMEOUT time is specified, the operation will timeout after time seconds, time should be specified as an integer. The INACTIVITY_TIMEOUT specifies an integer number of seconds of inactivity after which the operation should terminate. If EXPECTED_HASH ALGO=value is specified, the operation will verify that the downloaded file's actual hash matches the expected value, where ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512. If it does not match, the operation fails with an error. ("EXPECTED_MD5 sum" is short-hand for "EXPECTED_HASH MD5=sum".) If SHOW_PROGRESS is specified, progress information will be printed as status messages until the operation is complete. For https URLs CMake must be built with OpenSSL. TLS/SSL certificates are not checked by default. Set TLS_VERIFY to ON to check certificates and/or use EXPECTED_HASH to verify downloaded content. Set TLS_CAINFO to specify a custom Certificate Authority file. If either TLS option is not given CMake will check variables CMAKE_TLS_VERIFY and CMAKE_TLS_CAINFO, respectively.<br /></p> <p>UPLOAD will upload the given file to the given URL. If LOG var is specified a log of the upload will be put in var. If STATUS var is specified the status of the operation will be put in var. The status is returned in a list of length 2. The first element is the numeric return value for the operation, and the second element is a string value for the error. A 0 numeric error means no error in the operation. If TIMEOUT time is specified, the operation will timeout after time seconds, time should be specified as an integer. The INACTIVITY_TIMEOUT specifies an integer number of seconds of inactivity after which the operation should terminate. If SHOW_PROGRESS is specified, progress information will be printed as status messages until the operation is complete.<br /></p> <p>TIMESTAMP will write a string representation of the modification time of filename to variable.<br /></p> <p>Should the command be unable to obtain a timestamp variable will be set to the empty string "".<br /></p> <p>See documentation of the string TIMESTAMP sub-command for more details.<br /></p> <p>The file() command also provides COPY and INSTALL signatures:<br /></p> <pre> file(<COPY|INSTALL> files...

Relative input paths are evaluated with respect to the current source directory, and a relative destination is evaluated with respect to the current build directory. Copying preserves input file timestamps, and optimizes out a file if it exists at the destination with the same timestamp. Copying preserves input permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are given (default is USE_SOURCE_PERMISSIONS). See the install(DIRECTORY) command for documentation of permissions, PATTERN, REGEX, and EXCLUDE options. <br /></p> <p>The INSTALL signature differs slightly from COPY: it prints status messages, and NO_SOURCE_PERMISSIONS is default. Installation scripts generated by the install() command use this signature (with some undocumented options for internal use).<br /></p> <p>GENERATE will write an <output_file> with content from an <input_file>, or from <input_content>. The output is generated conditionally based on the content of the <condition>. The file is written at CMake generate-time and the input may contain generator expressions. The <condition>, <output_file> and <input_file> may also contain generator expressions. The <condition> must evaluate to either '0' or '1'.

Additional optional components may be listed after OPTIONAL_COMPONENTS. Available components and their influence on whether a package is considered to be found are defined by the target package.<br /></p> <p>The [version] argument requests a version with which the package found should be compatible (format is major[.minor[.patch[.tweak]]]). The EXACT option requests that the version be matched exactly. If no [version] and/or component list is given to a recursive invocation inside a find-module, the corresponding arguments are forwarded automatically from the outer call (including the EXACT flag for [version]). Version support is currently provided only on a package-by-package basis (details below).<br /></p> <p>User code should generally look for packages using the above simple signature. The remainder of this command documentation specifies the full command signature and details of the search process. Project maintainers wishing to provide a package to be found by this command are encouraged to read on.<br /></p> <p>The command has two modes by which it searches for packages: "Module" mode and "Config" mode. Module mode is available when the command is invoked with the above reduced signature. CMake searches for a file called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the CMake installation. If the file is found, it is read and processed by CMake. It is responsible for finding the package, checking the version, and producing any needed messages. Many find-modules provide limited or no support for versioning; check the module documentation. If no module is found and the MODULE option is not given the command proceeds to Config mode.<br /></p> <p>The complete Config mode command signature is:<br /></p> <pre> find_package(<package> [version] [EXACT] [QUIET]<br /> [REQUIRED] [[COMPONENTS] [components...]]<br /> [CONFIG|NO_MODULE]<br /> [NO_POLICY_SCOPE]<br /> [NAMES name1 [name2 ...]]<br /> [CONFIGS config1 [config2 ...]]<br /> [HINTS path1 [path2 ... ]]<br /> [PATHS path1 [path2 ... ]]<br /> [PATH_SUFFIXES suffix1 [suffix2 ...]]<br /> [NO_DEFAULT_PATH]<br /> [NO_CMAKE_ENVIRONMENT_PATH]<br /> [NO_CMAKE_PATH]<br /> [NO_SYSTEM_ENVIRONMENT_PATH]<br /> [NO_CMAKE_PACKAGE_REGISTRY]<br /> [NO_CMAKE_BUILDS_PATH]<br /> [NO_CMAKE_SYSTEM_PATH]<br /> [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]<br /> [CMAKE_FIND_ROOT_PATH_BOTH |<br /> ONLY_CMAKE_FIND_ROOT_PATH |<br /> NO_CMAKE_FIND_ROOT_PATH])<br /></pre> <p>The CONFIG option may be used to skip Module mode explicitly and switch to Config mode. It is synonymous to using NO_MODULE. Config mode is also implied by use of options not specified in the reduced signature. <br /></p> <p>Config mode attempts to locate a configuration file provided by the package to be found. A cache entry called <package>_DIR is created to hold the directory containing the file. By default the command searches for a package with the name <package>. If the NAMES option is given the names following it are used instead of <package>. The command searches for a file called "<name>Config.cmake" or "<lower-case-name>-config.cmake" for each name specified. A replacement set of possible configuration file names may be given using the CONFIGS option. The search procedure is specified below. Once found, the configuration file is read and processed by CMake. Since the file is provided by the package it already knows the location of package contents. The full path to the configuration file is stored in the cmake variable <package>_CONFIG.<br /></p> <p>All configuration files which have been considered by CMake while searching for an installation of the package with an appropriate version are stored in the cmake variable <package>_CONSIDERED_CONFIGS, the associated versions in <package>_CONSIDERED_VERSIONS. <br /></p> <p>If the package configuration file cannot be found CMake will generate an error describing the problem unless the QUIET argument is specified. If REQUIRED is specified and the package is not found a fatal error is generated and the configure step stops executing. If <package>_DIR has been set to a directory not containing a configuration file CMake will ignore it and search from scratch.<br /></p> <p>When the [version] argument is given Config mode will only find a version of the package that claims compatibility with the requested version (format is major[.minor[.patch[.tweak]]]). If the EXACT option is given only a version of the package claiming an exact match of the requested version may be found. CMake does not establish any convention for the meaning of version numbers. Package version numbers are checked by "version" files provided by the packages themselves. For a candidate package configuration file "<config-file>.cmake" the corresponding version file is located next to it and named either "<config-file>-version.cmake" or "<config-file>Version.cmake". If no such version file is available then the configuration file is assumed to not be compatible with any requested version. A basic version file containing generic version matching code can be created using the macro write_basic_package_version_file(), see its documentation for more details. When a version file is found it is loaded to check the requested version number. The version file is loaded in a nested scope in which the following variables have been defined:<br /></p> <pre> PACKAGE_FIND_NAME = the <package> name<br /> PACKAGE_FIND_VERSION = full requested version string<br /> PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0<br /> PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0<br /> PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0<br /> PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0<br /> PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4<br /></pre> <p>The version file checks whether it satisfies the requested version and sets these variables:<br /></p> <pre> PACKAGE_VERSION = full provided version string<br /> PACKAGE_VERSION_EXACT = true if version is exact match<br /> PACKAGE_VERSION_COMPATIBLE = true if version is compatible<br /> PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version<br /></pre> <p>These variables are checked by the find_package command to determine whether the configuration file provides an acceptable version. They are not available after the find_package call returns. If the version is acceptable the following variables are set:<br /></p> <pre> <package>_VERSION = full provided version string<br /> <package>_VERSION_MAJOR = major version if provided, else 0<br /> <package>_VERSION_MINOR = minor version if provided, else 0<br /> <package>_VERSION_PATCH = patch version if provided, else 0<br /> <package>_VERSION_TWEAK = tweak version if provided, else 0<br /> <package>_VERSION_COUNT = number of version components, 0 to 4<br /></pre> <p>and the corresponding package configuration file is loaded. When multiple package configuration files are available whose version files claim compatibility with the version requested it is unspecified which one is chosen. No attempt is made to choose a highest or closest version number.<br /></p> <p>Config mode provides an elaborate interface and search procedure. Much of the interface is provided for completeness and for use internally by find-modules loaded by Module mode. Most user code should simply call<br /></p> <pre> find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])<br /></pre> <p>in order to find a package. Package maintainers providing CMake package configuration files are encouraged to name and install them such that the procedure outlined below will find them without requiring use of additional options.<br /></p> <p>CMake constructs a set of possible installation prefixes for the package. Under each prefix several directories are searched for a configuration file. The tables below show the directories searched. Each entry is meant for installation trees following Windows (W), UNIX (U), or Apple (A) conventions.<br /></p> <pre> <prefix>/ (W)<br /> <prefix>/(cmake|CMake)/ (W)<br /> <prefix>/<name>*/ (W)<br /> <prefix>/<name>*/(cmake|CMake)/ (W)<br /> <prefix>/(lib/<arch>|lib|share)/cmake/<name>*/ (U)<br /> <prefix>/(lib/<arch>|lib|share)/<name>*/ (U)<br /> <prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/ (U)<br /></pre> <p>On systems supporting OS X Frameworks and Application Bundles the following directories are searched for frameworks or bundles containing a configuration file:<br /></p> <pre> <prefix>/<name>.framework/Resources/ (A)<br /> <prefix>/<name>.framework/Resources/CMake/ (A)<br /> <prefix>/<name>.framework/Versions/*/Resources/ (A)<br /> <prefix>/<name>.framework/Versions/*/Resources/CMake/ (A)<br /> <prefix>/<name>.app/Contents/Resources/ (A)<br /> <prefix>/<name>.app/Contents/Resources/CMake/ (A)<br /></pre> <p>In all cases the <name> is treated as case-insensitive and corresponds to any of the names specified (<package> or names given by NAMES). Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is set. If PATH_SUFFIXES is specified the suffixes are appended to each (W) or (U) directory entry one-by-one.<br /></p> <p>This set of directories is intended to work in cooperation with projects that provide configuration files in their installation trees. Directories above marked with (W) are intended for installations on Windows where the prefix may point at the top of an application's installation directory. Those marked with (U) are intended for installations on UNIX platforms where the prefix is shared by multiple packages. This is merely a convention, so all (W) and (U) directories are still searched on all platforms. Directories marked with (A) are intended for installations on Apple platforms. The cmake variables CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of preference as specified below.<br /></p> <p>The set of installation prefixes is constructed using the following steps. If NO_DEFAULT_PATH is specified all NO_* options are enabled.<br /></p> <p>1. Search paths specified in cmake-specific cache variables. These are intended to be used on the command line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH is passed.<br /></p> <pre> CMAKE_PREFIX_PATH<br /> CMAKE_FRAMEWORK_PATH<br /> CMAKE_APPBUNDLE_PATH<br /></pre> <p>2. Search paths specified in cmake-specific environment variables. These are intended to be set in the user's shell configuration. This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.<br /></p> <pre> <package>_DIR<br /> CMAKE_PREFIX_PATH<br /> CMAKE_FRAMEWORK_PATH<br /> CMAKE_APPBUNDLE_PATH<br /></pre> <p>3. Search paths specified by the HINTS option. These should be paths computed by system introspection, such as a hint provided by the location of another item already found. Hard-coded guesses should be specified with the PATHS option.<br /></p> <p>4. Search the standard system environment variables. This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed. Path entries ending in "/bin" or "/sbin" are automatically converted to their parent directories.<br /></p> <pre> PATH<br /></pre> <p>5. Search project build trees recently configured in a CMake GUI. This can be skipped if NO_CMAKE_BUILDS_PATH is passed. It is intended for the case when a user is building multiple dependent projects one after another.<br /></p> <p>6. Search paths stored in the CMake user package registry. This can be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed. On Windows a <package> may appear under registry key<br /></p> <pre> HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package><br /></pre> <p>as a REG_SZ value, with arbitrary name, that specifies the directory containing the package configuration file. On UNIX platforms a <package> may appear under the directory<br /></p> <pre> ~/.cmake/packages/<package><br /></pre> <p>as a file, with arbitrary name, whose content specifies the directory containing the package configuration file. See the export(PACKAGE) command to create user package registry entries for project build trees.<br /></p> <p>7. Search cmake variables defined in the Platform files for the current system. This can be skipped if NO_CMAKE_SYSTEM_PATH is passed.<br /></p> <pre> CMAKE_SYSTEM_PREFIX_PATH<br /> CMAKE_SYSTEM_FRAMEWORK_PATH<br /> CMAKE_SYSTEM_APPBUNDLE_PATH<br /></pre> <p>8. Search paths stored in the CMake system package registry. This can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed. On Windows a <package> may appear under registry key<br /></p> <pre> HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package><br /></pre> <p>as a REG_SZ value, with arbitrary name, that specifies the directory containing the package configuration file. There is no system package registry on non-Windows platforms.<br /></p> <p>9. Search paths specified by the PATHS option. These are typically hard-coded guesses.<br /></p> <p>On Darwin or systems supporting OS X Frameworks, the cmake variable CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:<br /></p> <pre> "FIRST" - Try to find frameworks before standard<br /> libraries or headers.

This is the default on Darwin.<br /> "LAST" - Try to find application bundles after standard<br /> programs.<br /> "ONLY" - Only try to find application bundles.<br /> "NEVER" - Never try to find application bundles.<br /></pre> <p>The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all other search directories. This effectively "re-roots" the entire search under given locations. By default it is empty. It is especially useful when cross-compiling to point to the root directory of the target environment and CMake will search there too. By default at first the directories listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_PACKAGE. This behavior can be manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.<br /></p> <p>The default search order is designed to be most-specific to least-specific for common use cases. Projects may override the order by simply calling the command multiple times and using the NO_* options:<br /></p> <pre> find_package(<package> PATHS paths... NO_DEFAULT_PATH)<br /> find_package(<package>)<br /></pre> <p>Once one of the calls succeeds the result variable will be set and stored in the cache so that no call will search again.<br /></p> <p>Every non-REQUIRED find_package() call can be disabled by setting the variable CMAKE_DISABLE_FIND_PACKAGE_<package> to TRUE. See the documentation for the CMAKE_DISABLE_FIND_PACKAGE_<package> variable for more information.<br /></p> <p>When loading a find module or package configuration file find_package defines variables to provide information about the call arguments (and restores their original state before returning):<br /></p> <pre> <package>_FIND_REQUIRED = true if REQUIRED option was given<br /> <package>_FIND_QUIETLY = true if QUIET option was given<br /> <package>_FIND_VERSION = full requested version string<br /> <package>_FIND_VERSION_MAJOR = major version if requested, else 0<br /> <package>_FIND_VERSION_MINOR = minor version if requested, else 0<br /> <package>_FIND_VERSION_PATCH = patch version if requested, else 0<br /> <package>_FIND_VERSION_TWEAK = tweak version if requested, else 0<br /> <package>_FIND_VERSION_COUNT = number of version components, 0 to 4<br /> <package>_FIND_VERSION_EXACT = true if EXACT option was given<br /> <package>_FIND_COMPONENTS = list of requested components<br /> <package>_FIND_REQUIRED_<c> = true if component <c> is required<br /> false if component <c> is optional<br /></pre> <p>In Module mode the loaded find module is responsible to honor the request detailed by these variables; see the find module for details. In Config mode find_package handles REQUIRED, QUIET, and version options automatically but leaves it to the package configuration file to handle components in a way that makes sense for the package. The package configuration file may set <package>_FOUND to false to tell find_package that component requirements are not satisfied.<br /></p> <p>See the cmake_policy() command documentation for discussion of the NO_POLICY_SCOPE option.</p> </li> <li> <a name="command:find_path"></a><b><code>find_path</code></b>: Find the directory containing a file.<br /> <pre> find_path(<VAR> name1 [path1 path2 ...])<br /></pre> <p>This is the short-hand signature for the command that is sufficient in many cases.

Rules specified by calls to this command within a source directory are executed in order during installation. The order across directories is not defined.<br /></p> <p>There are multiple signatures for this command. Some of them define installation properties for files and targets. Properties common to multiple signatures are covered here but they are valid only for signatures that specify them.<br /></p> <p>DESTINATION arguments specify the directory on disk to which a file will be installed. If a full path (with a leading slash or drive letter) is given it is used directly. If a relative path is given it is interpreted relative to the value of CMAKE_INSTALL_PREFIX. The prefix can be relocated at install time using DESTDIR mechanism explained in the CMAKE_INSTALL_PREFIX variable documentation.<br /></p> <p>PERMISSIONS arguments specify permissions for installed files. Valid permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ, GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE, SETUID, and SETGID. Permissions that do not make sense on certain platforms are ignored on those platforms.<br /></p> <p>The CONFIGURATIONS argument specifies a list of build configurations for which the install rule applies (Debug, Release, etc.).<br /></p> <p>The COMPONENT argument specifies an installation component name with which the install rule is associated, such as "runtime" or "development". During component-specific installation only install rules associated with the given component name will be executed. During a full installation all components are installed. If COMPONENT is not provided a default component "Unspecified" is created. The default component name may be controlled with the CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.<br /></p> <p>The RENAME argument specifies a name for an installed file that may be different from the original file. Renaming is allowed only when a single file is installed by the command.<br /></p> <p>The OPTIONAL argument specifies that it is not an error if the file to be installed does not exist. <br /></p> <p>The TARGETS signature:<br /></p> <pre> install(TARGETS targets...

There are five kinds of target files that may be installed: ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE. Executables are treated as RUNTIME targets, except that those marked with the MACOSX_BUNDLE property are treated as BUNDLE targets on OS X. Static libraries are always treated as ARCHIVE targets. Module libraries are always treated as LIBRARY targets. For non-DLL platforms shared libraries are treated as LIBRARY targets, except that those marked with the FRAMEWORK property are treated as FRAMEWORK targets on OS X. For DLL platforms the DLL part of a shared library is treated as a RUNTIME target and the corresponding import library is treated as an ARCHIVE target. All Windows-based systems including Cygwin are DLL platforms. The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments change the type of target to which the subsequent properties apply. If none is given the installation properties apply to all target types. If only one is given then only targets of that type will be installed (which can be used to install just a DLL or just an import library).The INCLUDES DESTINATION specifies a list of directories which will be added to the INTERFACE_INCLUDE_DIRECTORIES of the <targets> when exported by install(EXPORT). If a relative path is specified, it is treated as relative to the $<INSTALL_PREFIX>.<br /></p> <p>The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause subsequent properties to be applied to installing a FRAMEWORK shared library target's associated files on non-Apple platforms. Rules defined by these arguments are ignored on Apple platforms because the associated files are installed into the appropriate locations inside the framework folder. See documentation of the PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE target properties for details.<br /></p> <p>Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY option. On some platforms a versioned shared library has a symbolic link such as<br /></p> <pre> lib<name>.so -> lib<name>.so.1<br /></pre> <p>where "lib<name>.so.1" is the soname of the library and "lib<name>.so" is a "namelink" allowing linkers to find the library when given "-l<name>". The NAMELINK_ONLY option causes installation of only the namelink when a library target is installed. The NAMELINK_SKIP option causes installation of library files other than the namelink when a library target is installed. When neither option is given both portions are installed. On platforms where versioned shared libraries do not have namelinks or when a library is not versioned the NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option installs nothing. See the VERSION and SOVERSION target properties for details on creating versioned shared libraries.<br /></p> <p>One or more groups of properties may be specified in a single call to the TARGETS form of this command. A target may be installed more than once to different locations. Consider hypothetical targets "myExe", "mySharedLib", and "myStaticLib". The code<br /></p> <pre> install(TARGETS myExe mySharedLib myStaticLib<br /> RUNTIME DESTINATION bin<br /> LIBRARY DESTINATION lib<br /> ARCHIVE DESTINATION lib/static)<br /> install(TARGETS mySharedLib DESTINATION /some/full/path)<br /></pre> <p>will install myExe to <prefix>/bin and myStaticLib to <prefix>/lib/static. On non-DLL platforms mySharedLib will be installed to <prefix>/lib and /some/full/path. On DLL platforms the mySharedLib DLL will be installed to <prefix>/bin and /some/full/path and its import library will be installed to <prefix>/lib/static and /some/full/path.<br /></p> <p>The EXPORT option associates the installed target files with an export called <export-name>. It must appear before any RUNTIME, LIBRARY, or ARCHIVE options. To actually install the export file itself, call install(EXPORT). See documentation of the install(EXPORT ...) signature below for details.<br /></p> <p>Installing a target with EXCLUDE_FROM_ALL set to true has undefined behavior.<br /></p> <p>The FILES signature:<br /></p> <pre> install(FILES files... DESTINATION <dir><br /> [PERMISSIONS permissions...]<br /> [CONFIGURATIONS [Debug|Release|...]]<br /> [COMPONENT <component>]<br /> [RENAME <name>] [OPTIONAL])<br /></pre> <p>The FILES form specifies rules for installing files for a project. File names given as relative paths are interpreted with respect to the current source directory. Files installed by this form are by default given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ if no PERMISSIONS argument is given.<br /></p> <p>The PROGRAMS signature:<br /></p> <pre> install(PROGRAMS files... DESTINATION <dir><br /> [PERMISSIONS permissions...]<br /> [CONFIGURATIONS [Debug|Release|...]]<br /> [COMPONENT <component>]<br /> [RENAME <name>] [OPTIONAL])<br /></pre> <p>The PROGRAMS form is identical to the FILES form except that the default permissions for the installed file also include OWNER_EXECUTE, GROUP_EXECUTE, and WORLD_EXECUTE. This form is intended to install programs that are not targets, such as shell scripts. Use the TARGETS form to install targets built within the project.<br /></p> <p>The DIRECTORY signature:<br /></p> <pre> install(DIRECTORY dirs... DESTINATION <dir><br /> [FILE_PERMISSIONS permissions...]<br /> [DIRECTORY_PERMISSIONS permissions...]<br /> [USE_SOURCE_PERMISSIONS] [OPTIONAL]<br /> [CONFIGURATIONS [Debug|Release|...]]<br /> [COMPONENT <component>] [FILES_MATCHING]<br /> [[PATTERN <pattern> | REGEX <regex>]<br /> [EXCLUDE] [PERMISSIONS permissions...]] [...])<br /></pre> <p>The DIRECTORY form installs contents of one or more directories to a given destination. The directory structure is copied verbatim to the destination. The last component of each directory name is appended to the destination directory but a trailing slash may be used to avoid this because it leaves the last component empty. Directory names given as relative paths are interpreted with respect to the current source directory. If no input directory names are given the destination directory will be created but nothing will be installed into it. The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options specify permissions given to files and directories in the destination. If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not, file permissions will be copied from the source directory structure. If no permissions are specified files will be given the default permissions specified in the FILES form of the command, and the directories will be given the default permissions specified in the PROGRAMS form of the command.<br /></p> <p>Installation of directories may be controlled with fine granularity using the PATTERN or REGEX options. These "match" options specify a globbing pattern or regular expression to match directories or files encountered within input directories. They may be used to apply certain options (see below) to a subset of the files and directories encountered. The full path to each input file or directory (with forward slashes) is matched against the expression. A PATTERN will match only complete file names: the portion of the full path matching the pattern must occur at the end of the file name and be preceded by a slash. A REGEX will match any portion of the full path but it may use '/' and '$' to simulate the PATTERN behavior. By default all files and directories are installed whether or not they are matched. The FILES_MATCHING option may be given before the first match option to disable installation of files (but not directories) not matched by any expression. For example, the code<br /></p> <pre> install(DIRECTORY src/ DESTINATION include/myproj<br /> FILES_MATCHING PATTERN "*.h")<br /></pre> <p>will extract and install header files from a source tree.<br /></p> <p>Some options may follow a PATTERN or REGEX expression and are applied only to files or directories matching them. The EXCLUDE option will skip the matched file or directory. The PERMISSIONS option overrides the permissions setting for the matched file or directory. For example the code<br /></p> <pre> install(DIRECTORY icons scripts/ DESTINATION share/myproj<br /> PATTERN "CVS" EXCLUDE<br /> PATTERN "scripts/*"<br /> PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ<br /> GROUP_EXECUTE GROUP_READ)<br /></pre> <p>will install the icons directory to share/myproj/icons and the scripts directory to share/myproj. The icons will get default file permissions, the scripts will be given specific permissions, and any CVS directories will be excluded.<br /></p> <p>The SCRIPT and CODE signature:<br /></p> <pre> install([[SCRIPT <file>] [CODE <code>]] [...])<br /></pre> <p>The SCRIPT form will invoke the given CMake script files during installation. If the script file name is a relative path it will be interpreted with respect to the current source directory. The CODE form will invoke the given CMake code during installation. Code is specified as a single argument inside a double-quoted string. For example, the code<br /></p> <pre> install(CODE "MESSAGE(\"Sample install message.\")")<br /></pre> <p>will print a message during installation.<br /></p> <p>The EXPORT signature:<br /></p> <pre> install(EXPORT <export-name> DESTINATION <dir><br /> [NAMESPACE <namespace>] [FILE <name>.cmake]<br /> [PERMISSIONS permissions...]<br /> [CONFIGURATIONS [Debug|Release|...]]<br /> [EXPORT_LINK_INTERFACE_LIBRARIES]<br /> [COMPONENT <component>])<br /></pre> <p>The EXPORT form generates and installs a CMake file containing code to import targets from the installation tree into another project. Target installations are associated with the export <export-name> using the EXPORT option of the install(TARGETS ...) signature documented above. The NAMESPACE option will prepend <namespace> to the target names as they are written to the import file. By default the generated file will be called <export-name>.cmake but the FILE option may be used to specify a different name. The value given to the FILE option must be a file name with the ".cmake" extension. If a CONFIGURATIONS option is given then the file will only be installed when one of the named configurations is installed. Additionally, the generated import file will reference only the matching target configurations. The EXPORT_LINK_INTERFACE_LIBRARIES keyword, if present, causes the contents of the properties matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)? to be exported, when policy CMP0022 is NEW. If a COMPONENT option is specified that does not match that given to the targets associated with <export-name> the behavior is undefined. If a library target is included in the export but a target to which it links is not included the behavior is unspecified.<br /></p> <p>The EXPORT form is useful to help outside projects use targets built and installed by the current project. For example, the code<br /></p> <pre> install(TARGETS myexe EXPORT myproj DESTINATION bin)<br /> install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)<br /></pre> <p>will install the executable myexe to <prefix>/bin and code to import it in the file "<prefix>/lib/myproj/myproj.cmake". An outside project may load this file with the include command and reference the myexe executable from the installation tree using the imported target name mp_myexe as if the target were built in its own tree.<br /></p> <p>NOTE: This command supercedes the INSTALL_TARGETS command and the target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT. It also replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS commands. The processing order of these install rules relative to those generated by INSTALL_TARGETS, INSTALL_FILES, and INSTALL_PROGRAMS commands is not defined.<br /></p> </li> <li> <a name="command:link_directories"></a><b><code>link_directories</code></b>: Specify directories in which the linker will look for libraries.<br /> <pre> link_directories(directory1 directory2 ...)<br /></pre> <p>Specify the paths in which the linker should search for libraries. The command will apply only to targets created after it is called. Relative paths given to this command are interpreted as relative to the current source directory, see CMP0015. <br /></p> <p>Note that this command is rarely necessary. Library locations returned by find_package() and find_library() are absolute paths. Pass these absolute library file paths directly to the target_link_libraries() command. CMake will ensure the linker finds them.</p> </li> <li> <a name="command:list"></a><b><code>list</code></b>: List operations.<br /> <pre> list(LENGTH <list> <output variable>)<br /> list(GET <list> <element index> [<element index> ...]<br /> <output variable>)<br /> list(APPEND <list> <element> [<element> ...])<br /> list(FIND <list> <value> <output variable>)<br /> list(INSERT <list> <element_index> <element> [<element> ...])<br /> list(REMOVE_ITEM <list> <value> [<value> ...])<br /> list(REMOVE_AT <list> <index> [<index> ...])<br /> list(REMOVE_DUPLICATES <list>)<br /> list(REVERSE <list>)<br /> list(SORT <list>)<br /></pre> <p>LENGTH will return a given list's length.<br /></p> <p>GET will return list of elements specified by indices from the list.<br /></p> <p>APPEND will append elements to the list.<br /></p> <p>FIND will return the index of the element specified in the list or -1 if it wasn't found.<br /></p> <p>INSERT will insert elements to the list to the specified location.<br /></p> <p>REMOVE_AT and REMOVE_ITEM will remove items from the list. The difference is that REMOVE_ITEM will remove the given items, while REMOVE_AT will remove the items at the given indices.<br /></p> <p>REMOVE_DUPLICATES will remove duplicated items in the list.<br /></p> <p>REVERSE reverses the contents of the list in-place.<br /></p> <p>SORT sorts the list in-place alphabetically.<br /></p> <p>The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM, REMOVE_DUPLICATES, REVERSE and SORT may create new values for the list within the current CMake variable scope. Similar to the SET command, the LIST command creates new variable values in the current scope, even if the list itself is actually defined in a parent scope. To propagate the results of these operations upwards, use SET with PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value propagation.<br /></p> <p>NOTES: A list in cmake is a ; separated group of strings. To create a list the set command can be used. For example, set(var a b c d e) creates a list with a;b;c;d;e, and set(var "a b c d e") creates a string or a list with one item in it.<br /></p> <p>When specifying index values, if <element index> is 0 or greater, it is indexed from the beginning of the list, with 0 representing the first list element. If <element index> is -1 or lesser, it is indexed from the end of the list, with -1 representing the last list element. Be careful when counting with negative indices: they do not start from 0. -0 is equivalent to 0, the first list element.<br /></p> </li> <li> <a name="command:load_cache"></a><b><code>load_cache</code></b>: Load in the values from another project's CMake cache.<br /> <pre> load_cache(pathToCacheFile READ_WITH_PREFIX<br /> prefix entry1...)<br /></pre> <p>Read the cache and store the requested entries in variables with their name prefixed with the given prefix.

Commands listed after macro, but before the matching endmacro, are not invoked until the macro is invoked. When it is invoked, the commands recorded in the macro are first modified by replacing formal parameters (${arg1}) with the arguments passed, and then invoked as normal commands. In addition to referencing the formal parameters you can reference the values ${ARGC} which will be set to the number of arguments passed into the function as well as ${ARGV0} ${ARGV1} ${ARGV2} ... which will have the actual values of the arguments passed in. This facilitates creating macros with optional arguments. Additionally ${ARGV} holds the list of all arguments given to the macro and ${ARGN} holds the list of arguments past the last expected argument. Note that the parameters to a macro and values such as ARGN are not variables in the usual CMake sense. They are string replacements much like the C preprocessor would do with a macro. If you want true CMake variables and/or better CMake scope control you should look at the function command.<br /></p> <p>See the cmake_policy() command documentation for the behavior of policies inside macros.</p> </li> <li> <a name="command:mark_as_advanced"></a><b><code>mark_as_advanced</code></b>: Mark cmake cached variables as advanced.<br /> <pre> mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)<br /></pre> <p>Mark the named cached variables as advanced.

Normally, set will set a regular CMake variable. If CACHE is present, then the <variable> is put in the cache instead, unless it is already in the cache. See section 'Variable types in CMake' below for details of regular and cache variables and their interactions. If CACHE is used, <type> and <docstring> are required. <type> is used by the CMake GUI to choose a widget with which the user sets a value. The value for <type> may be one of<br /></p> <pre> FILEPATH = File chooser dialog.<br /> PATH = Directory chooser dialog.<br /> STRING = Arbitrary string.<br /> BOOL = Boolean ON/OFF checkbox.<br /> INTERNAL = No GUI entry (used for persistent variables).<br /></pre> <p>If <type> is INTERNAL, the cache variable is marked as internal, and will not be shown to the user in tools like cmake-gui. This is intended for values that should be persisted in the cache, but which users should not normally change. INTERNAL implies FORCE.<br /></p> <p>Normally, set(...CACHE...) creates cache variables, but does not modify them.

See also: the unset() command.<br /></p> <pre> set(<variable> <value1> ... <valueN>)<br /></pre> <p>In this case <variable> is set to a semicolon separated list of values.<br /></p> <p><variable> can be an environment variable such as:<br /></p> <pre> set( ENV{PATH} /home/martink )<br /></pre> <p>in which case the environment variable will be set.<br /></p> <p>*** Variable types in CMake ***<br /></p> <p>In CMake there are two types of variables: normal variables and cache variables. Normal variables are meant for the internal use of the script (just like variables in most programming languages); they are not persisted across CMake runs. Cache variables (unless set with INTERNAL) are mostly intended for configuration settings where the first CMake run determines a suitable default value, which the user can then override, by editing the cache with tools such as ccmake or cmake-gui. Cache variables are stored in the CMake cache file, and are persisted across CMake runs. <br /></p> <p>Both types can exist at the same time with the same name but different values. When ${FOO} is evaluated, CMake first looks for a normal variable 'FOO' in scope and uses it if set. If and only if no normal variable exists then it falls back to the cache variable 'FOO'.<br /></p> <p>Some examples:<br /></p> <p>The code 'set(FOO "x")' sets the normal variable 'FOO'. It does not touch the cache, but it will hide any existing cache value 'FOO'.<br /></p> <p>The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache, ignoring any normal variable of the same name. If 'FOO' is in the cache then nothing happens to either the normal variable or the cache variable. If 'FOO' is not in the cache, then it is added to the cache.<br /></p> <p>Finally, whenever a cache variable is added or modified by a command, CMake also *removes* the normal variable of the same name from the current scope so that an immediately following evaluation of it will expose the newly cached value.<br /></p> <p>Normally projects should avoid using normal and cache variables of the same name, as this interaction can be hard to follow. However, in some situations it can be useful. One example (used by some projects):<br /></p> <p>A project has a subproject in its source tree. The child project has its own CMakeLists.txt, which is included from the parent CMakeLists.txt using add_subdirectory(). Now, if the parent and the child project provide the same option (for example a compiler option), the parent gets the first chance to add a user-editable option to the cache. Normally, the child would then use the same value that the parent uses. However, it may be necessary to hard-code the value for the child project's option while still allowing the user to edit the value used by the parent project. The parent project can achieve this simply by setting a normal variable with the same name as the option in a scope sufficient to hide the option's cache variable from the child completely. The parent has already set the cache variable, so the child's set(...CACHE...) will do nothing, and evaluating the option variable will use the value from the normal variable, which hides the cache variable.</p> </li> <li> <a name="command:set_directory_properties"></a><b><code>set_directory_properties</code></b>: Set a property of the directory.<br /> <pre> set_directory_properties(PROPERTIES prop1 value1 prop2 value2)<br /></pre> <p>Set a property for the current directory and subdirectories. If the property is not found, CMake will report an error. The properties include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES, INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES. ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as a part of "make clean" stage.</p> </li> <li> <a name="command:set_property"></a><b><code>set_property</code></b>: Set a named property in a given scope.<br /> <pre> set_property(<GLOBAL |<br /> DIRECTORY [dir] |<br /> TARGET [target1 [target2 ...]] |<br /> SOURCE [src1 [src2 ...]] |<br /> TEST [test1 [test2 ...]] |<br /> CACHE [entry1 [entry2 ...]]><br /> [APPEND] [APPEND_STRING]<br /> PROPERTY <name> [value1 [value2 ...]])<br /></pre> <p>Set one property on zero or more objects of a scope. The first argument determines the scope in which the property is set. It must be one of the following:<br /></p> <p>GLOBAL scope is unique and does not accept a name.<br /></p> <p>DIRECTORY scope defaults to the current directory but another directory (already processed by CMake) may be named by full or relative path.<br /></p> <p>TARGET scope may name zero or more existing targets.<br /></p> <p>SOURCE scope may name zero or more source files. Note that source file properties are visible only to targets added in the same directory (CMakeLists.txt).<br /></p> <p>TEST scope may name zero or more existing tests.<br /></p> <p>CACHE scope must name zero or more cache existing entries.<br /></p> <p>The required PROPERTY option is immediately followed by the name of the property to set. Remaining arguments are used to compose the property value in the form of a semicolon-separated list. If the APPEND option is given the list is appended to any existing property value.If the APPEND_STRING option is given the string is append to any existing property value as string, i.e. it results in a longer string and not a list of strings.</p> </li> <li> <a name="command:set_source_files_properties"></a><b><code>set_source_files_properties</code></b>: Source files can have properties that affect how they are built.<br /> <pre> set_source_files_properties([file1 [file2 [...]]]<br /> PROPERTIES prop1 value1<br /> [prop2 value2 [...]])<br /></pre> <p>Set properties associated with source files using a key/value paired list.

The syntax for the command is to list all the files you want to change, and then provide the values you want to set next. You can use any prop value pair you want and extract it later with the GET_TARGET_PROPERTY command.<br /></p> <p>Properties that affect the name of a target's output file are as follows. The PREFIX and SUFFIX properties override the default target name prefix (such as "lib") and suffix (such as ".so"). IMPORT_PREFIX and IMPORT_SUFFIX are the equivalent properties for the import library corresponding to a DLL (for SHARED library targets). OUTPUT_NAME sets the real name of a target when it is built and can be used to help create two targets of the same name even though CMake requires unique logical target names. There is also a <CONFIG>_OUTPUT_NAME that can set the output name on a per-configuration basis. <CONFIG>_POSTFIX sets a postfix for the real name of the target when it is built under the configuration named by <CONFIG> (in upper-case, such as "DEBUG_POSTFIX"). The value of this property is initialized when the target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX (except for executable targets because earlier CMake versions which did not use this variable for executables).<br /></p> <p>The LINK_FLAGS property can be used to add extra flags to the link step of a target. LINK_FLAGS_<CONFIG> will add to the configuration <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO. DEFINE_SYMBOL sets the name of the preprocessor symbol defined when compiling sources in a shared library. If not set here then it is set to target_EXPORTS by default (with some substitutions if the target is not a valid C identifier). This is useful for headers to know whether they are being included from inside their library or outside to properly setup dllexport/dllimport decorations. The COMPILE_FLAGS property sets additional compiler flags used to build sources within the target. It may also be used to pass additional preprocessor definitions.<br /></p> <p>The LINKER_LANGUAGE property is used to change the tool used to link an executable or shared library. The default is set the language to match the files in the library. CXX and C are common values for this property.<br /></p> <p>For shared libraries VERSION and SOVERSION can be used to specify the build version and API version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so-names. If only one of both is specified the missing is assumed to have the same version number. For executables VERSION can be used to specify the build version. When building or installing appropriate symlinks are created if the platform supports symlinks. For shared libraries and executables on Windows the VERSION attribute is parsed to extract a "major.minor" version number. These numbers are used as the image version of the binary. <br /></p> <p>There are a few properties used to specify RPATH rules. INSTALL_RPATH is a semicolon-separated list specifying the rpath to use in installed targets (for platforms that support it). INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the project to the INSTALL_RPATH. SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an rpath allowing the target to run from the build tree. BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in the build tree with the INSTALL_RPATH. This takes precedence over SKIP_BUILD_RPATH and avoids the need for relinking before installation. INSTALL_NAME_DIR is a string specifying the directory portion of the "install_name" field of shared libraries on Mac OSX to use in the installed targets. When the target is created the values of the variables CMAKE_INSTALL_RPATH, CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to initialize these properties.<br /></p> <p>PROJECT_LABEL can be used to change the name of the target in an IDE like visual studio. VS_KEYWORD can be set to change the visual studio keyword, for example Qt integration works better if this is set to Qt4VSv1.0.<br /></p> <p>VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER and VS_SCC_AUXPATH can be set to add support for source control bindings in a Visual Studio project file.<br /></p> <p>VS_GLOBAL_<variable> can be set to add a Visual Studio project-specific global variable. Qt integration works better if VS_GLOBAL_QtVersion is set to the Qt version FindQt4.cmake found. For example, "4.7.3"<br /></p> <p>The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts to run before and after installing a target. They are used only when the old INSTALL_TARGETS command is used to install the target. Use the INSTALL command instead.<br /></p> <p>The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio generators. If it is set to 1 the target will not be part of the default build when you select "Build Solution". This can also be set on a per-configuration basis using EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>.</p> </li> <li> <a name="command:set_tests_properties"></a><b><code>set_tests_properties</code></b>: Set a property of the tests.<br /> <pre> set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)<br /></pre> <p>Set a property for the tests.

The "optimized" keyword corresponds to all other configurations. The "general" keyword corresponds to all configurations, and is purely optional (assumed if omitted). Higher granularity may be achieved for per-configuration rules by creating and linking to IMPORTED library targets. See the IMPORTED mode of the add_library command for more information. <br /></p> <p>Library dependencies are transitive by default with this signature. When this target is linked into another target then the libraries linked to this target will appear on the link line for the other target too.

Prefer the INTERFACE mode instead. Libraries specified as "debug" are wrapped in a generator expression to correspond to debug builds. If policy CMP0022 is not NEW, the libraries are also appended to the LINK_INTERFACE_LIBRARIES_DEBUG property (or to the properties corresponding to configurations listed in the DEBUG_CONFIGURATIONS global property if it is set). Libraries specified as "optimized" are appended to the INTERFACE_LINK_LIBRARIES property. If policy CMP0022 is not NEW, they are also appended to the LINK_INTERFACE_LIBRARIES property.

If policy CMP0022 is not NEW, they are also made part of the LINK_INTERFACE_LIBRARIES. Libraries and targets following LINK_PRIVATE are linked to, but are not made part of the INTERFACE_LINK_LIBRARIES (or LINK_INTERFACE_LIBRARIES).<br /></p> <p>The library dependency graph is normally acyclic (a DAG), but in the case of mutually-dependent STATIC libraries CMake allows the graph to contain cycles (strongly connected components). When another target links to one of the libraries CMake repeats the entire connected component. For example, the code<br /></p> <pre> add_library(A STATIC a.c)<br /> add_library(B STATIC b.c)<br /> target_link_libraries(A B)<br /> target_link_libraries(B A)<br /> add_executable(main main.c)<br /> target_link_libraries(main A)<br /></pre> <p>links 'main' to 'A B A B'.

These variables are RUN_RESULT_VAR (explanation see above) and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an additional cache variable RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to hold stdout and stderr from the executable.<br /></p> <p>In order to make cross compiling your project easier, use try_run only if really required. If you use try_run, use RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) only if really required. Using them will require that when crosscompiling, the cache variables will have to be set manually to the output of the executable.

Executables are always treated as runtime targets. Static libraries are always treated as archive targets. Module libraries are always treated as library targets. For non-DLL platforms shared libraries are treated as library targets.

Currently Qt4 and Qt5 are supported. When this property is set to TRUE, CMake will scan the source files at build time and invoke moc accordingly. If an #include statement like #include "moc_foo.cpp" is found, the Q_OBJECT class declaration is expected in the header, and moc is run on the header file. If an #include statement like #include "foo.moc" is found, then a Q_OBJECT is expected in the current source file and moc is run on the file itself. Additionally, all header files are parsed for Q_OBJECT macros, and if found, moc is also executed on those files. The resulting moc files, which are not included as shown above in any of the source files are included in a generated <targetname>_automoc.cpp file, which is compiled as part of the target.This property is initialized by the value of the variable CMAKE_AUTOMOC if it is set when a target is created.<br /></p> <p>Additional command line options for moc can be set via the AUTOMOC_MOC_OPTIONS property.<br /></p> <p>By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules for searching the files which will be processed by moc can be relaxed. See the documentation for this variable for more details.<br /></p> <p>The global property AUTOMOC_TARGETS_FOLDER can be used to group the automoc targets together in an IDE, e.g. in MSVS.</p> </li> <li> <a name="prop_tgt:AUTOMOC_MOC_OPTIONS"></a><b><code>AUTOMOC_MOC_OPTIONS</code></b>: Additional options for moc when using automoc (see the AUTOMOC property)<br /> <p>This property is only used if the AUTOMOC property is set to TRUE for this target. In this case, it holds additional command line options which will be used when moc is executed during the build, i.e. it is equivalent to the optional OPTIONS argument of the qt4_wrap_cpp() macro.<br /></p> <p>By default it is empty.</p> </li> <li> <a name="prop_tgt:BUILD_WITH_INSTALL_RPATH"></a><b><code>BUILD_WITH_INSTALL_RPATH</code></b>: Should build tree targets have install tree rpaths.<br /> <p>BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in the build tree with the INSTALL_RPATH. This takes precedence over SKIP_BUILD_RPATH and avoids the need for relinking before installation. This property is initialized by the value of the variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is created.</p> </li> <li> <a name="prop_tgt:BUNDLE"></a><b><code>BUNDLE</code></b>: This target is a CFBundle on the Mac.<br /> <p>If a module library target has this property set to true it will be built as a CFBundle when built on the mac.

For example, if a property "FOO" appears in the list, then for each dependee, the "INTERFACE_FOO" property content in all of its dependencies must be consistent with each other, and with the "FOO" property in the dependee. Consistency in this sense has the meaning that if the property is set, then it must have the same boolean value as all others, and if the property is not set, then it is ignored. Note that for each dependee, the set of properties from this property must not intersect with the set of properties from the COMPATIBLE_INTERFACE_STRING property.</p> </li> <li> <a name="prop_tgt:COMPATIBLE_INTERFACE_STRING"></a><b><code>COMPATIBLE_INTERFACE_STRING</code></b>: Properties which must be string-compatible with their link interface<br /> <p>The COMPATIBLE_INTERFACE_STRING property may contain a list of properties for this target which must be the same when evaluated as a string in the INTERFACE of all linked dependees. For example, if a property "FOO" appears in the list, then for each dependee, the "INTERFACE_FOO" property content in all of its dependencies must be equal with each other, and with the "FOO" property in the dependee. If the property is not set, then it is ignored. Note that for each dependee, the set of properties from this property must not intersect with the set of properties from the COMPATIBLE_INTERFACE_BOOL property.</p> </li> <li> <a name="prop_tgt:COMPILE_DEFINITIONS"></a><b><code>COMPILE_DEFINITIONS</code></b>: Preprocessor definitions for compiling a target's sources.<br /> <p>The COMPILE_DEFINITIONS property may be set to a semicolon-separated list of preprocessor definitions using the syntax VAR or VAR=value. Function-style definitions are not supported. CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values). This property may be set on a per-configuration basis using the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").<br /></p> <p>CMake will automatically drop some definitions that are not supported by the native build tool. The VS6 IDE does not support definition values with spaces (but NMake does).<br /></p> <p>Contents of COMPILE_DEFINITIONS may use "generator expressions" with the syntax "$<...>". Generator expressions are evaluated during build system generation to produce information specific to each build configuration. Valid expressions are:<br /></p> <pre> $<0:...> = empty string (ignores "...")<br /> $<1:...> = content of "..."<br /> $<CONFIG:cfg> = '1' if config is "cfg", else '0'<br /> $<CONFIGURATION> = configuration name<br /> $<BOOL:...> = '1' if the '...' is true, else '0'<br /> $<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'<br /> $<ANGLE-R> = A literal '>'. Used to compare strings which contain a '>' for example.<br /> $<COMMA> = A literal ','. Used to compare strings which contain a ',' for example.<br /> $<SEMICOLON> = A literal ';'.

Although the property was originally introduced for this purpose, it is no longer necessary. If the generated header file is created by a custom command in the same target as the source file, the automatic dependency scanning process will recognize the dependency.

See the TARGETS form of the INSTALL command to create installation rules for targets built by cmake.<br /></p> <p>The directory <dir> is relative to the installation prefix, which is stored in the variable CMAKE_INSTALL_PREFIX.</p> </li> <li> <a name="command:install_targets"></a><b><code>install_targets</code></b>: Deprecated. Use the install(TARGETS ) command instead.<br /> <p>This command has been superceded by the install command. It is provided for compatibility with older CMake code.<br /></p> <pre> install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)<br /></pre> <p>Create rules to install the listed targets into the given directory. The directory <dir> is relative to the installation prefix, which is stored in the variable CMAKE_INSTALL_PREFIX. If RUNTIME_DIRECTORY is specified, then on systems with special runtime files (Windows DLL), the files will be copied to that directory.</p> </li> <li> <a name="command:link_libraries"></a><b><code>link_libraries</code></b>: Deprecated. Use the target_link_libraries() command instead.<br /> <p>Link libraries to all targets added later.<br /></p> <pre> link_libraries(library1 <debug | optimized> library2 ...)<br /></pre> <p>Specify a list of libraries to be linked into any following targets (typically added with the add_executable or add_library calls). This command is passed down to all subdirectories. The debug and optimized strings may be used to indicate that the next library listed is to be used only for that specific type of build.</p> </li> <li> <a name="command:make_directory"></a><b><code>make_directory</code></b>: Deprecated. Use the file(MAKE_DIRECTORY ) command instead.<br /> <pre> make_directory(directory)<br /></pre> <p>Creates the specified directory. Full paths should be given. Any parent directories that do not exist will also be created. Use with care.</p> </li> <li> <a name="command:output_required_files"></a><b><code>output_required_files</code></b>: Deprecated. Approximate C preprocessor dependency scanning.<br /> <p>This command exists only because ancient CMake versions provided it. CMake handles preprocessor dependency scanning automatically using a more advanced scanner.<br /></p> <pre> output_required_files(srcfile outputfile)<br /></pre> <p>Outputs a list of all the source files that are required by the specified srcfile. This list is written into outputfile. This is similar to writing out the dependencies for srcfile except that it jumps from .h files into .cxx, .c and .cpp files if possible.</p> </li> <li> <a name="command:remove"></a><b><code>remove</code></b>: Deprecated. Use the list(REMOVE_ITEM ) command instead.<br /> <pre> remove(VAR VALUE VALUE ...)<br /></pre> <p>Removes VALUE from the variable VAR. This is typically used to remove entries from a vector (e.g. semicolon separated list). VALUE is expanded.</p> </li> <li> <a name="command:subdir_depends"></a><b><code>subdir_depends</code></b>: Deprecated. Does nothing.<br /> <pre> subdir_depends(subdir dep1 dep2 ...)<br /></pre> <p>Does not do anything. This command used to help projects order parallel builds correctly. This functionality is now automatic.</p> </li> <li> <a name="command:subdirs"></a><b><code>subdirs</code></b>: Deprecated. Use the add_subdirectory() command instead.<br /> <p>Add a list of subdirectories to the build.<br /></p> <pre> subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]<br /> [PREORDER] )<br /></pre> <p>Add a list of subdirectories to the build. The add_subdirectory command should be used instead of subdirs although subdirs will still work. This will cause any CMakeLists.txt files in the sub directories to be processed by CMake. Any directories after the PREORDER flag are traversed first by makefile builds, the PREORDER flag has no effect on IDE projects. Any directories after the EXCLUDE_FROM_ALL marker will not be included in the top level makefile or project file. This is useful for having CMake create makefiles or projects for a set of examples in a project. You would want CMake to generate makefiles or project files for all the examples at the same time, but you would not want them to show up in the top level project or be built each time make is run from the top.</p> </li> <li> <a name="command:use_mangled_mesa"></a><b><code>use_mangled_mesa</code></b>: Copy mesa headers for use in combination with system GL.<br /> <pre> use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)<br /></pre> <p>The path to mesa includes, should contain gl_mangle.h. The mesa headers are copied to the specified output directory. This allows mangled mesa headers to override other GL headers by being added to the include directory path earlier.</p> </li> <li> <a name="command:utility_source"></a><b><code>utility_source</code></b>: Specify the source tree of a third-party utility.<br /> <pre> utility_source(cache_entry executable_name<br /> path_to_source [file1 file2 ...])<br /></pre> <p>When a third-party utility's source is included in the distribution, this command specifies its location and name. The cache entry will not be set unless the path_to_source and all listed files exist. It is assumed that the source tree of the utility will have been built before it is needed.<br /></p> <p>When cross compiling CMake will print a warning if a utility_source() command is executed, because in many cases it is used to build an executable which is executed later on. This doesn't work when cross compiling, since the executable can run only on their target platform. So in this case the cache entry has to be adjusted manually so it points to an executable which is runnable on the build host.</p> </li> <li> <a name="command:variable_requires"></a><b><code>variable_requires</code></b>: Deprecated. Use the if() command instead.<br /> <p>Assert satisfaction of an option's required variables.<br /></p> <pre> variable_requires(TEST_VARIABLE RESULT_VARIABLE<br /> REQUIRED_VARIABLE1<br /> REQUIRED_VARIABLE2 ...)<br /></pre> <p>The first argument (TEST_VARIABLE) is the name of the variable to be tested, if that variable is false nothing else is done. If TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a variable that is set to true if all the required variables are set. The rest of the arguments are variables that must be true or not set to NOTFOUND to avoid an error. If any are not true, an error is reported.</p> </li> <li> <a name="command:write_file"></a><b><code>write_file</code></b>: Deprecated. Use the file(WRITE ) command instead.<br /> <pre> write_file(filename "message to write"... [APPEND])<br /></pre> <p>The first argument is the file name, the rest of the arguments are messages to write. If the argument APPEND is specified, then the message will be appended.<br /></p> <p>NOTE 1: file(WRITE ... and file(APPEND ... do exactly the same as this one but add some more functionality.<br /></p> <p>NOTE 2: When using write_file the produced file cannot be used as an input to CMake (CONFIGURE_FILE, source file ...) because it will lead to an infinite loop. Use configure_file if you want to generate input files to CMake.</p> </li> </ul> <h2><a name="section_StandardCMakeModules"></a>Standard CMake Modules</h2> <ul> <li><a

This has the effect that the resulting FooConfig.cmake file would work poorly under Windows and OSX, where users are used to choose the install location of a binary package at install time, independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time.<br /></p> <p>Using CONFIGURE_PACKAGE_CONFIG_FILE() helps. If used correctly, it makes the resulting FooConfig.cmake file relocatable. Usage:<br /></p> <pre> 1. write a FooConfig.cmake.in file as you are used to<br /> 2. insert a line containing only the string "@PACKAGE_INIT@"<br /> 3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")<br /> (this must be after the @PACKAGE_INIT@ line)<br /> 4. instead of using the normal configure_file(), use CONFIGURE_PACKAGE_CONFIG_FILE()<br /></pre> <p><br /></p> <p>The <input> and <output> arguments are the input and output file, the same way as in configure_file().<br /></p> <p>The <path> given to INSTALL_DESTINATION must be the destination where the FooConfig.cmake file will be installed to. This can either be a relative or absolute path, both work.<br /></p> <p>The variables <var1> to <varN> given as PATH_VARS are the variables which contain install destinations. For each of them the macro will create a helper variable PACKAGE_<var...>. These helper variables must be used in the FooConfig.cmake.in file for setting the installed location. They are calculated by CONFIGURE_PACKAGE_CONFIG_FILE() so that they are always relative to the installed location of the package. This works both for relative and also for absolute locations. For absolute locations it works only if the absolute location is a subdirectory of CMAKE_INSTALL_PREFIX.<br /></p> <p>By default configure_package_config_file() also generates two helper macros, set_and_check() and check_required_components() into the FooConfig.cmake file.<br /></p> <p>set_and_check() should be used instead of the normal set() command for setting directories and file locations. Additionally to setting the variable it also checks that the referenced file or directory actually exists and fails with a FATAL_ERROR otherwise. This makes sure that the created FooConfig.cmake file does not contain wrong references. When using the NO_SET_AND_CHECK_MACRO, this macro is not generated into the FooConfig.cmake file.<br /></p> <p>check_required_components(<package_name>) should be called at the end of the FooConfig.cmake file if the package supports components. This macro checks whether all requested, non-optional components have been found, and if this is not the case, sets the Foo_FOUND variable to FALSE, so that the package is considered to be not found. It does that by testing the Foo_<Component>_FOUND variables for all requested required components. When using the NO_CHECK_REQUIRED_COMPONENTS option, this macro is not generated into the FooConfig.cmake file.<br /></p> <p>For an example see below the documentation for WRITE_BASIC_PACKAGE_VERSION_FILE().<br /></p> <p><br /></p> <pre> WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )<br /></pre> <p><br /></p> <p>Writes a file for use as <package>ConfigVersion.cmake file to <filename>. See the documentation of find_package() for details on this.<br /></p> <pre> filename is the output filename, it should be in the build tree.<br /> major.minor.patch is the version number of the project to be installed<br /></pre> <p>The COMPATIBILITY mode AnyNewerVersion means that the installed package version will be considered compatible if it is newer or exactly the same as the requested version. This mode should be used for packages which are fully backward compatible, also across major versions. If SameMajorVersion is used instead, then the behaviour differs from AnyNewerVersion in that the major version number must be the same as requested, e.g. version 2.0 will not be considered compatible if 1.0 is requested. This mode should be used for packages which guarantee backward compatibility within the same major version. If ExactVersion is used, then the package is only considered compatible if the requested version matches exactly its own version number (not considering the tweak version). For example, version 1.2.3 of a package is only considered compatible to requested version 1.2.3. This mode is for packages without compatibility guarantees. If your project has more elaborated version matching rules, you will need to write your own custom ConfigVersion.cmake file instead of using this macro.<br /></p> <p>Internally, this macro executes configure_file() to create the resulting version file. Depending on the COMPATIBLITY, either the file BasicConfigVersion-SameMajorVersion.cmake.in or BasicConfigVersion-AnyNewerVersion.cmake.in is used. Please note that these two files are internal to CMake and you should not call configure_file() on them yourself, but they can be used as starting point to create more sophisticted custom ConfigVersion.cmake files.<br /></p> <p><br /></p> <p>Example using both configure_package_config_file() and write_basic_package_version_file(): CMakeLists.txt:<br /></p> <pre> set(INCLUDE_INSTALL_DIR include/ ...

The generated binary installers contain everything installed via CMake's INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).<br /></p> <p>For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. See CPackComponent module for that.<br /></p> <p>The CPACK_GENERATOR variable has different meanings in different contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a *list of generators*: when run with no other arguments, CPack will iterate over that list and produce one package for each generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming a single generator*. If you need per-cpack- generator logic to control *other* cpack settings, then you need a CPACK_PROJECT_CONFIG_FILE.<br /></p> <p>The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE. See the top level file CMakeCPackOptions.cmake.in for an example.<br /></p> <p>If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a per-generator basis. It only need contain overrides.<br /></p> <p>Here's how it works:<br /></p> <pre> - cpack runs<br /> - it includes CPackConfig.cmake<br /> - it iterates over the generators listed in that file's<br /> CPACK_GENERATOR list variable (unless told to use just a<br /> specific one via -G on the command line...)<br /></pre> <p><br /></p> <pre> - foreach generator, it then<br /> - sets CPACK_GENERATOR to the one currently being iterated<br /> - includes the CPACK_PROJECT_CONFIG_FILE<br /> - produces the package for that generator<br /></pre> <p><br /></p> <p>This is the key: For each generator listed in CPACK_GENERATOR in CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to *the one currently being used* and then include the CPACK_PROJECT_CONFIG_FILE.<br /></p> <p>Before including this CPack module in your CMakeLists.txt file, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:<br /></p> <pre> CPACK_PACKAGE_NAME - The name of the package (or application). If<br /> not specified, defaults to the project name.<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,<br /> "Kitware").<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its<br /> packaging. If it is not set then this will default (internally) to the<br /> build dir. This variable may be defined in CPack config file or from<br /> the cpack command line option "-B". If set the command line option<br /> override the value found in the config file.<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_VERSION_MAJOR - Package major Version<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_VERSION_MINOR - Package minor Version<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_VERSION_PATCH - Package patch Version<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the<br /> project.

For example, cmake-2.6.1-Linux-i686.<br /> The default value is<br /></pre> <p><br /></p> <pre> ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the<br /> target system. This may be used by some CPack generators<br /> like NSIS to create an installation directory e.g., "CMake 2.5"<br /> below the installation prefix. All installed element will be<br /> put inside this directory.<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_ICON - A branding image that will be displayed inside<br /> the installer (used by GUI installers).<br /></pre> <p><br /></p> <pre> CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration<br /> file. This file included at cpack time, once per<br /> generator after CPack has set CPACK_GENERATOR to the actual generator<br /> being used. It allows per-generator setting of CPACK_* variables at<br /> cpack time.<br /></pre> <p><br /></p> <pre> CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It<br /> will typically be displayed to the user by the produced installer<br /> (often with an explicit "Accept" button, for graphical installers)<br /> prior to installation. This license file is NOT added to installed<br /> file but is used by some CPack generators like NSIS. If you want<br /> to install a license file (may be the same as this one)<br /> along with your project you must add an appropriate CMake INSTALL<br /> command in your CMakeLists.txt.<br /></pre> <p><br /></p> <pre> CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It<br /> typically describes in some detail the purpose of the project<br /> during the installation. Not all CPack generators uses<br /> this file.<br /></pre> <p><br /></p> <pre> CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the<br /> installer. It welcomes users to this installer.<br /> Typically used in the graphical installers on Windows and Mac OS X.<br /></pre> <p><br /></p> <pre> CPACK_MONOLITHIC_INSTALL - Disables the component-based<br /> installation mechanism. When set the component specification is ignored<br /> and all installed items are put in a single "MONOLITHIC" package.<br /> Some CPack generators do monolithic packaging by default and<br /> may be asked to do component packaging by setting<br /> CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.<br /></pre> <p><br /></p> <pre> CPACK_GENERATOR - List of CPack generators to use. If not<br /> specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,<br /> CPACK_BINARY_NSIS) allowing the user to enable/disable individual<br /> generators. This variable may be used on the command line<br /> as well as in:<br /></pre> <p><br /></p> <pre> cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree<br /></pre> <p><br /></p> <pre> CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration<br /> file.

Defaults to CPackConfig.cmake.<br /></pre> <p><br /></p> <pre> CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated<br /> text label to be used to create Start Menu shortcuts. For example,<br /> setting this to the list ccmake;CMake will<br /> create a shortcut named "CMake" that will execute the installed<br /> executable ccmake. Not all CPack generators use it (at least NSIS and<br /> OSXX11 do).<br /></pre> <p><br /></p> <pre> CPACK_STRIP_FILES - List of files to be stripped. Starting with<br /> CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which<br /> enables stripping of all files (a list of files evaluates to TRUE<br /> in CMake, so this change is compatible).<br /></pre> <p><br /></p> <p>The following CPack variables are specific to source packages, and will not affect binary packages:<br /></p> <pre> CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For<br /> example cmake-2.6.1.<br /></pre> <p><br /></p> <pre> CPACK_SOURCE_STRIP_FILES - List of files in the source tree that<br /> will be stripped. Starting with CMake 2.6.0<br /> CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables<br /> stripping of all files (a list of files evaluates to TRUE in CMake,<br /> so this change is compatible).<br /></pre> <p><br /></p> <pre> CPACK_SOURCE_GENERATOR - List of generators used for the source<br /> packages.

See CPack module for general information about CPack.<br /></p> <p>For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COMPONENT argument of CMake's INSTALL command.

For each downloadable component, CPack will create an archive containing the contents of that component, which should be uploaded to the given site. When the user selects that component for installation, the installer will download and extract the component in place. This feature is useful for creating small installers that only download the requested components, saving bandwidth. Additionally, the installers are small enough that they will be installed as part of the normal installation process, and the "Change" button in Windows Add/Remove Programs control panel will allow one to add or remove parts of the application after the original installation.

One may get more detailed reports by adding<br /></p> <pre> set(CTEST_USE_LAUNCHERS 1)<br /></pre> <p>to the CTestConfig.cmake file. When this option is enabled, the CTest module tells CMake's Makefile generators to invoke every command in the generated build system through a CTest launcher program. (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile generators.) During a manual build each launcher transparently runs the command it wraps. During a CTest-driven build for submission to CDash each launcher reports detailed information when its command fails or warns. (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but also adds the launcher overhead even for manual builds.

Both cmake and ctest need to know the value of it for the launchers to work properly. CMake needs to know in order to generate proper build rules, and ctest, in order to produce the proper error and warning analysis.<br /></p> <p>For convenience, you may set the ENV variable CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S script, too. Then, as long as your CMakeLists uses include(CTest) or include(CTestUseLaunchers), it will use the value of the ENV variable to initialize a CTEST_USE_LAUNCHERS cache variable.

The source tree must contain either a real data file at <name> or a "content link" at <name><ext> containing a hash of the real file using a hash algorithm corresponding to <ext>.

A list of URL templates must be provided in the variable ExternalData_URL_TEMPLATES using the placeholders "%(algo)" and "%(hash)" in each template.

If the source tree contains a content link such as "MyInput.png.md5" then the "MyData" target creates a real "MyInput.png" in the build tree.<br /></p> <p>The DATA{} syntax can be told to fetch a file series using the form "DATA{<name>,:}", where the ":" is literal. If the source tree contains a group of files or content links named like a series then a reference to one member adds rules to fetch all of them. Although all members of a series are fetched, only the file originally named by the DATA{} argument is substituted for it. The default configuration recognizes file series names ending with "#.ext", "_#.ext", ".#.ext", or "-#.ext" where "#" is a sequence of decimal digits and ".ext" is any single extension. Configure it with a regex that parses <number> and <suffix> parts from the end of <name>:<br /></p> <pre> ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$<br /></pre> <p>For more complicated cases set:<br /></p> <pre> ExternalData_SERIES_PARSE = regex with at least two () groups<br /> ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any<br /> ExternalData_SERIES_PARSE_NUMBER = <number> regex group number<br /> ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number<br /></pre> <p>Configure series number matching with a regex that matches the <number> part of series members named <prefix><number><suffix>:<br /></p> <pre> ExternalData_SERIES_MATCH = regex matching <number> in all series members<br /></pre> <p>Note that the <suffix> of a series does not include a hash-algorithm extension.<br /></p> <p>The DATA{} syntax can alternatively match files associated with the named file and contained in the same directory. Associated files may be specified by options using the syntax DATA{<name>,<opt1>,<opt2>,...}. Each option may specify one file by name or specify a regular expression to match file names using the syntax REGEX:<regex>. For example, the arguments<br /></p> <pre> DATA{MyData/MyInput.mhd,MyInput.img} # File pair<br /> DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series<br /></pre> <p>will pass MyInput.mha and MyFrames00.png on the command line but ensure that the associated files are present next to them.<br /></p> <p>The DATA{} syntax may reference a directory using a trailing slash and a list of associated files. The form DATA{<name>/,<opt1>,<opt2>,...} adds rules to fetch any files in the directory that match one of the associated file options. For example, the argument DATA{MyDataDir/,REGEX:.*} will pass the full path to a MyDataDir directory on the command line and ensure that the directory contains files corresponding to every file or content link in the MyDataDir source directory.<br /></p> <p>The variable ExternalData_LINK_CONTENT may be set to the name of a supported hash algorithm to enable automatic conversion of real data files referenced by the DATA{} syntax into content links. For each such <file> a content link named "<file><ext>" is created. The original file is renamed to the form ".ExternalData_<algo>_<hash>" to stage it for future transmission to one of the locations in the list of URL templates (by means outside the scope of this module). The data fetch rule created for the content link will use the staged object if it cannot be found using any URL template.<br /></p> <p>The variable ExternalData_OBJECT_STORES may be set to a list of local directories that store objects using the layout <dir>/%(algo)/%(hash). These directories will be searched first for a needed object. If the object is not available in any store then it will be fetched remotely using the URL templates and added to the first local store listed. If no stores are specified the default is a location inside the build tree.<br /></p> <p>The variable ExternalData_SOURCE_ROOT may be set to the highest source directory containing any path named by a DATA{} reference. The default is CMAKE_SOURCE_DIR. ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer to directories within a single source distribution (e.g. they come together in one tarball).<br /></p> <p>The variable ExternalData_BINARY_ROOT may be set to the directory to hold the real data files named by expanded DATA{} references. The default is CMAKE_BINARY_DIR.

At build time the commands will be executed in order and aborted if any one fails. For example:<br /></p> <pre> ... BUILD_COMMAND make COMMAND echo done ...<br /></pre> <p>specifies to run "make" and then "echo done" during the build step.

If you invoke a custom target that depends on a step halfway through the step dependency chain, then all the previous steps will also run to ensure everything is up to date.<br /></p> <p>For example, to drive configure, build and test steps independently for each ExternalProject_Add call in your project, write the following line prior to any ExternalProject_Add calls in your CMakeLists file:<br /></p> <pre> set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)<br /></pre> </li> <li> <a name="module:FeatureSummary"></a><b><code>FeatureSummary</code></b>: Macros for generating a summary of enabled/disabled features<br /> <p><br /></p> <p>This module provides the macros feature_summary(), set_package_properties() and add_feature_info().

Here you specify what information will be printed:<br /></p> <pre> ALL: print everything<br /> ENABLED_FEATURES: the list of all features which are enabled<br /> DISABLED_FEATURES: the list of all features which are disabled<br /> PACKAGES_FOUND: the list of all packages which have been found<br /> PACKAGES_NOT_FOUND: the list of all packages which have not been found<br /> OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL<br /> OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL<br /> RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED<br /> RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED<br /> REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED<br /> REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED<br /> RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME<br /> RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME<br /></pre> <p><br /></p> <p>If a FILENAME is given, the information is printed into this file.

Ideally this is set already directly in the Find-module.<br /></p> <p>TYPE: What type of dependency has the using project on that package. Default is OPTIONAL. In this case it is a package which can be used by the project when available at buildtime, but it also work without. RECOMMENDED is similar to OPTIONAL, i.e. the project will build if the package is not present, but the functionality of the resulting binaries will be severly limited. If a REQUIRED package is not available at buildtime, the project may not even build. This can be combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for feature_summary(). Last, a RUNTIME package is a package which is actually not used at all during the build, but which is required for actually running the resulting binaries. So if such a package is missing, the project can still be built, but it may not work later on. If set_package_properties() is called multiple times for the same package with different TYPEs, the TYPE is only changed to higher TYPEs ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are ignored. The TYPE property is project-specific, so it cannot be set by the Find-module, but must be set in the project.<br /></p> <p>PURPOSE: This describes which features this package enables in the project, i.e. it tells the user what functionality he gets in the resulting binaries. If set_package_properties() is called multiple times for a package, all PURPOSE properties are appended to a list of purposes of the package in the project.

This requires matching libraries to be linked explicitly or available in the link library search path. In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve dynamic linking. Boost automatic linking typically requests static libraries with a few exceptions (such as Boost.Python).

CUDA_FOUND will report if an acceptable version of CUDA was found.<br /></p> <p>The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be determined by the location of nvcc in the system path and REQUIRED is specified to find_package(). To use a different installed version of the toolkit set the environment variable CUDA_BIN_PATH before running cmake (e.g. CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.

This helps make the<br /> generated host code match the rest of the system better. Sometimes<br /> certain flags give nvcc problems, and this will help you turn the flag<br /> propagation off. This does not affect the flags supplied directly to nvcc<br /> via CUDA_NVCC_FLAGS or through the OPTION flags specified through<br /> CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.

All of the non CUDA C files are compiled using the standard<br /> build rules specified by CMAKE and the cuda files are compiled to object<br /> files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is<br /> added automatically to include_directories(). Some standard CMake target<br /> calls can be used on the target after calling this macro<br /> (e.g. set_target_properties and target_link_libraries), but setting<br /> properties that adjust compilation flags will not affect code compiled by<br /> nvcc. Such flags should be modified before calling CUDA_ADD_EXECUTABLE,<br /> CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.<br /></pre> <p><br /></p> <pre> CUDA_ADD_LIBRARY( cuda_target file0 file1 ...<br /> [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )<br /> -- Same as CUDA_ADD_EXECUTABLE except that a library is created.<br /></pre> <p><br /></p> <pre> CUDA_BUILD_CLEAN_TARGET()<br /> -- Creates a convience target that deletes all the dependency files<br /> generated.

This file name is typically passed into<br /> CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS. output_file_var is produced<br /> based on cuda_target the list of objects files that need separable<br /> compilation as specified by object_files. If the object_files list is<br /> empty, then output_file_var will be empty. This function is called<br /> automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE. Note that<br /> this is a function and not a macro.<br /></pre> <p><br /></p> <pre> CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )<br /> -- Sets the directories that should be passed to nvcc<br /> (e.g. nvcc -Ipath0 -Ipath1 ... ).

This is called automatically for CUDA_ADD_EXECUTABLE and<br /> CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS<br /> directly. When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the<br /> nvcc_flags passed in are the same as the flags passed in via the OPTIONS<br /> argument. The only nvcc flag added automatically is the bitness flag as<br /> specified by CUDA_64_BIT_DEVICE_CODE. Note that this is a function<br /> instead of a macro.<br /></pre> <p><br /></p> <pre> CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...<br /> [STATIC | SHARED | MODULE] [OPTIONS ...] )<br /> -- This is where all the magic happens.

Files that don't end with .cu<br /> or have the HEADER_FILE_ONLY property are ignored.<br /></pre> <p><br /></p> <pre> The arguments passed in after OPTIONS are extra command line options to<br /> give to nvcc. You can also specify per configuration options by<br /> specifying the name of the configuration followed by the options. General<br /> options must preceed configuration specific options.

This is because when you add the<br /> cuda file to Visual Studio it knows that this file produces an object file<br /> and will link in the resulting object file automatically.<br /></pre> <p><br /></p> <pre> This script will also generate a separate cmake script that is used at<br /> build time to invoke nvcc. This is for several reasons.<br /></pre> <p><br /></p> <pre> 1. nvcc can return negative numbers as return values which confuses<br /> Visual Studio into thinking that the command succeeded. The script now<br /> checks the error codes and produces errors when there was a problem.<br /></pre> <p><br /></p> <pre> 2. nvcc has been known to not delete incomplete results when it<br /> encounters problems. This confuses build systems into thinking the<br /> target was generated when in fact an unusable file exists. The script<br /> now deletes the output files if there was an error.<br /></pre> <p><br /></p> <pre> 3. By putting all the options that affect the build into a file and then<br /> make the build rule dependent on the file, the output files will be<br /> regenerated when the options change.<br /></pre> <p><br /></p> <pre> This script also looks at optional arguments STATIC, SHARED, or MODULE to<br /> determine when to target the object compilation for a shared library.<br /> BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in<br /> CUDA_ADD_LIBRARY. On some systems special flags are added for building<br /> objects intended for shared libraries. A preprocessor macro,<br /> <target_name>_EXPORTS is defined when a shared library compilation is<br /> detected.<br /></pre> <p><br /></p> <pre> Flags passed into add_definitions with -D or /D are passed along to nvcc.<br /></pre> <p><br /></p> <p>The script defines the following variables:<br /></p> <pre> CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc.<br /> CUDA_VERSION_MINOR -- The minor version.<br /> CUDA_VERSION<br /> CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR<br /></pre> <p><br /></p> <pre> CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).<br /> CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK.

The first argument in both modes is the name of the Find-module where it is called (in original casing).<br /></p> <p>The first simple mode looks like this:<br /></p> <pre> FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )<br /></pre> <p>If the variables <var1> to <varN> are all valid, then <UPPERCASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given as second argument, then the function will generate itself useful success and error messages. You can also supply a custom error message for the failure case. This is not recommended.<br /></p> <p>The second mode is more powerful and also supports version checking:<br /></p> <pre> FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [FOUND_VAR <resultVar>]<br /> [REQUIRED_VARS <var1>...<varN>]<br /> [VERSION_VAR <versionvar>]<br /> [HANDLE_COMPONENTS]<br /> [CONFIG_MODE]<br /> [FAIL_MESSAGE "Custom failure message"] )<br /></pre> <p><br /></p> <p>In this mode, the name of the result-variable can be set either to either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the FOUND_VAR option. Other names for the result-variable are not allowed. So for a Find-module named FindFooBar.cmake, the two possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended to use the original case version. If the FOUND_VAR option is not used, the default is <UPPERCASED_NAME>_FOUND.<br /></p> <p>As in the simple mode, if <var1> through <varN> are all valid, <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the variables which are required for this package are listed. Following VERSION_VAR the name of the variable can be specified which holds the version of the package which has been found. If this is done, this version will be checked against the (potentially) specified required version used in the find_package() call. The EXACT keyword is also handled. The default messages include information about the required version and the version which has been actually found, both if the version is ok or not. If the package supports components, use the HANDLE_COMPONENTS option to enable handling them. In this case, find_package_handle_standard_args() will report which components have been found and which are missing, and the <packagename>_FOUND variable will be set to FALSE if any of the required components (i.e. not the ones listed after OPTIONAL_COMPONENTS) are missing. Use the option CONFIG_MODE if your FindXXX.cmake module is a wrapper for a find_package(... NO_MODULE) call. In this case VERSION_VAR will be set to <NAME>_VERSION and the macro will automatically check whether the Config module was found. Via FAIL_MESSAGE a custom failure message can be specified, if this is not used, the default message will be displayed.<br /></p> <p>Example for mode 1:<br /></p> <pre> find_package_handle_standard_args(LibXml2 DEFAULT_MSG LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)<br /></pre> <p><br /></p> <p>LibXml2 is considered to be found, if both LIBXML2_LIBRARY and LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE. If it is not found and REQUIRED was used, it fails with FATAL_ERROR, independent whether QUIET was used or not. If it is found, success will be reported, including the content of <var1>. On repeated Cmake runs, the same message won't be printed again.<br /></p> <p>Example for mode 2:<br /></p> <pre> find_package_handle_standard_args(LibXslt FOUND_VAR LibXslt_FOUND<br /> REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS<br /> VERSION_VAR LibXslt_VERSION_STRING)<br /></pre> <p>In this case, LibXslt is considered to be found if the variable(s) listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and LibXslt_INCLUDE_DIRS in this case. The result will then be stored in LibXslt_FOUND . Also the version of LibXslt will be checked by using the version contained in LibXslt_VERSION_STRING. Since no FAIL_MESSAGE is given, the default messages will be printed.<br /></p> <p>Another example for mode 2:<br /></p> <pre> find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)<br /> find_package_handle_standard_args(Automoc4 CONFIG_MODE)<br /></pre> <p>In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4 NO_MODULE) and adds an additional search directory for automoc4. Here the result will be stored in AUTOMOC4_FOUND. The following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper success/error message.</p> </li> <li> <a name="module:FindPackageMessage"></a><b><code>FindPackageMessage</code></b>: <br /> <p>FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")<br /></p> <p>This macro is intended to be used in FindXXX.cmake modules files. It will print a message once for each unique find result. This is useful for telling the user where a package was found. The first argument specifies the name (XXX) of the package.

This module is a bit more complicated than the other FindSDL* family modules. The reason is that SDL_sound can be compiled in a large variety of different ways which are independent of platform. SDL_sound may dynamically link against other 3rd party libraries to get additional codec support, such as Ogg Vorbis, SMPEG, ModPlug, MikMod, FLAC, Speex, and potentially others. Under some circumstances which I don't fully understand, there seems to be a requirement that dependent libraries of libraries you use must also be explicitly linked against in order to successfully compile. SDL_sound does not currently have any system in place to know how it was compiled. So this CMake module does the hard work in trying to discover which 3rd party libraries are required for building (if any). This module uses a brute force approach to create a test program that uses SDL_sound, and then tries to build it. If the build fails, it parses the error output for known symbol names to figure out which libraries are needed.<br /></p> <p>Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.<br /></p> <p>On OSX, this will prefer the Framework version (if found) over others.

All macros require raw names in both lower case and upper case. The MACRO_NAMESPACE option replaces the default "FortranCInterface_" prefix with a given namespace "<macro-ns>".<br /></p> <p>The SYMBOLS option lists symbols to mangle automatically with C preprocessor definitions:<br /></p> <pre> <function> ==> #define <ns><function> ...<br /> <module>:<function> ==> #define <ns><module>_<function> ...<br /></pre> <p>If the mangling for some symbol is not known then no preprocessor definition is created, and a warning is displayed.

This policy has been put in place so users trying to build the project may be told when they need to update their CMake. Specifying a version also helps the project build with CMake versions newer than that specified. Use the cmake_minimum_required command at the top of your main CMakeLists.txt file:<br /></p> <pre> cmake_minimum_required(VERSION <major>.<minor>)<br /></pre> <p>where "<major>.<minor>" is the version of CMake you want to support (such as "2.6").

Consider the code<br /></p> <pre> target_link_libraries(myexe /path/to/libA.so)<br /></pre> <p>CMake 2.4 and below implemented linking to libraries whose full paths are known by splitting them on the link line into separate components consisting of the linker search path and the library name. The example code might have produced something like<br /></p> <pre> ... -L/path/to -lA ...<br /></pre> <p>in order to link to library A. An analysis was performed to order multiple link directories such that the linker would find library A in the desired location, but there are cases in which this does not work. CMake versions 2.6 and above use the more reliable approach of passing the full path to libraries directly to the linker in most cases. The example code now produces something like<br /></p> <pre> ... /path/to/libA.so ....<br /></pre> <p>Unfortunately this change can break code like<br /></p> <pre> target_link_libraries(myexe /path/to/libA.so B)<br /></pre> <p>where "B" is meant to find "/path/to/libB.so". This code is wrong because the user is asking the linker to find library B but has not provided a linker search path (which may be added with the link_directories command). However, with the old linking implementation the code would work accidentally because the linker search path added for library A allowed library B to be found.<br /></p> <p>In order to support projects depending on linker search paths added by linking to libraries with known full paths, the OLD behavior for this policy will add the linker search paths even though they are not needed for their own libraries. When this policy is set to OLD, CMake will produce a link line such as<br /></p> <pre> ... -L/path/to /path/to/libA.so -lB ...<br /></pre> <p>which will allow library B to be found as it was previously. When this policy is set to NEW, CMake will produce a link line such as<br /></p> <pre> ... /path/to/libA.so -lB ...<br /></pre> <p>which more accurately matches what the project specified.<br /></p> <p>The setting for this policy used when generating the link line is that in effect when the target is created by an add_executable or add_library command. For the example described above, the code<br /></p> <pre> cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)<br /> add_executable(myexe myexe.c)<br /> target_link_libraries(myexe /path/to/libA.so B)<br /></pre> <p>will work and suppress the warning for this policy. It may also be updated to work with the corrected linking approach:<br /></p> <pre> cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)<br /> link_directories(/path/to) # needed to find library B<br /> add_executable(myexe myexe.c)<br /> target_link_libraries(myexe /path/to/libA.so B)<br /></pre> <p>Even better, library B may be specified with a full path:<br /></p> <pre> add_executable(myexe myexe.c)<br /> target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)<br /></pre> <p>When all items on the link line have known paths CMake does not check this policy so it has no effect.<br /></p> <p>Note that the warning for this policy will be issued for at most one target. This avoids flooding users with messages for every target when setting the policy once will probably fix all targets.<br /></p> <p>This policy was introduced in CMake version 2.6.0.

The INTERFACE_LINK_LIBRARIES target property was introduced as a replacement in CMake 2.8.12. This new property is named consistently with the INTERFACE_COMPILE_DEFINITIONS, INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_OPTIONS properties. For in-build targets, CMake will use the INTERFACE_LINK_LIBRARIES property as the source of the link interface only if policy CMP0022 is NEW. When exporting a target which has this policy set to NEW, only the INTERFACE_LINK_LIBRARIES property will be processed and generated for the IMPORTED target by default. A new option to the install(EXPORT) and export commands allows export of the old-style properties for compatibility with downstream users of CMake versions older than 2.8.12. The target_link_libraries command will no longer populate the properties matching LINK_INTERFACE_LIBRARIES(_<CONFIG>)? if this policy is NEW.<br /></p> <p>The OLD behavior for this policy is to ignore the INTERFACE_LINK_LIBRARIES property for in-build targets. The NEW behavior for this policy is to use the INTERFACE_LINK_LIBRARIES property for in-build targets, and ignore the old properties matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?.<br /></p> <p>This policy was introduced in CMake version 2.8.12. CMake version 2.8.12.2 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly.</p> </li> <li> <a name="policy:CMP0023"></a><b><code>CMP0023</code></b>: Plain and keyword target_link_libraries signatures cannot be mixed.<br /> <p>CMake 2.8.12 introduced the target_link_libraries signature using the PUBLIC, PRIVATE, and INTERFACE keywords to generalize the LINK_PUBLIC and LINK_PRIVATE keywords introduced in CMake 2.8.7. Use of signatures with any of these keywords sets the link interface of a target explicitly, even if empty. This produces confusing behavior when used in combination with the historical behavior of the plain target_link_libraries signature. For example, consider the code:<br /></p> <pre> target_link_libraries(mylib A)<br /> target_link_libraries(mylib PRIVATE B)<br /></pre> <p>After the first line the link interface has not been set explicitly so CMake would use the link implementation, A, as the link interface. However, the second line sets the link interface to empty. In order to avoid this subtle behavior CMake now prefers to disallow mixing the plain and keyword signatures of target_link_libraries for a single target.<br /></p> <p>The OLD behavior for this policy is to allow keyword and plain target_link_libraries signatures to be mixed. The NEW behavior for this policy is to not to allow mixing of the keyword and plain signatures.<br /></p> <p>This policy was introduced in CMake version 2.8.12. CMake version 2.8.12.2 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly.</p> </li> </ul> <h2><a name="section_Variables"></a>Variables</h2> <h2><a name="section_VariablesThatChangeBehavior"></a>Variables That Change Behavior</h2> <ul> <li><a href="#variable:BUILD_SHARED_LIBS"><b><code>BUILD_SHARED_LIBS</code></b></a></li> <li><a href="#variable:CMAKE_ABSOLUTE_DESTINATION_FILES"><b><code>CMAKE_ABSOLUTE_DESTINATION_FILES</code></b></a></li> <li><a href="#variable:CMAKE_AUTOMOC_RELAXED_MODE"><b><code>CMAKE_AUTOMOC_RELAXED_MODE</code></b></a></li> <li><a href="#variable:CMAKE_BACKWARDS_COMPATIBILITY"><b><code>CMAKE_BACKWARDS_COMPATIBILITY</code></b></a></li> <li><a href="#variable:CMAKE_BUILD_TYPE"><b><code>CMAKE_BUILD_TYPE</code></b></a></li> <li><a href="#variable:CMAKE_COLOR_MAKEFILE"><b><code>CMAKE_COLOR_MAKEFILE</code></b></a></li> <li><a href="#variable:CMAKE_CONFIGURATION_TYPES"><b><code>CMAKE_CONFIGURATION_TYPES</code></b></a></li> <li><a href="#variable:CMAKE_DEBUG_TARGET_PROPERTIES"><b><code>CMAKE_DEBUG_TARGET_PROPERTIES</code></b></a></li> <li><a href="#variable:CMAKE_DISABLE_FIND_PACKAGE_PackageName"><b><code>CMAKE_DISABLE_FIND_PACKAGE_<PackageName></code></b></a></li> <li><a href="#variable:CMAKE_ERROR_DEPRECATED"><b><code>CMAKE_ERROR_DEPRECATED</code></b></a></li> <li><a href="#variable:CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION"><b><code>CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION</code></b></a></li> <li><a href="#variable:CMAKE_FIND_LIBRARY_PREFIXES"><b><code>CMAKE_FIND_LIBRARY_PREFIXES</code></b></a></li> <li><a href="#variable:CMAKE_FIND_LIBRARY_SUFFIXES"><b><code>CMAKE_FIND_LIBRARY_SUFFIXES</code></b></a></li> <li><a href="#variable:CMAKE_FIND_PACKAGE_WARN_NO_MODULE"><b><code>CMAKE_FIND_PACKAGE_WARN_NO_MODULE</code></b></a></li> <li><a href="#variable:CMAKE_IGNORE_PATH"><b><code>CMAKE_IGNORE_PATH</code></b></a></li> <li><a href="#variable:CMAKE_INCLUDE_PATH"><b><code>CMAKE_INCLUDE_PATH</code></b></a></li> <li><a href="#variable:CMAKE_INSTALL_DEFAULT_COMPONENT_NAME"><b><code>CMAKE_INSTALL_DEFAULT_COMPONENT_NAME</code></b></a></li> <li><a href="#variable:CMAKE_INSTALL_PREFIX"><b><code>CMAKE_INSTALL_PREFIX</code></b></a></li> <li><a href="#variable:CMAKE_LIBRARY_PATH"><b><code>CMAKE_LIBRARY_PATH</code></b></a></li> <li><a href="#variable:CMAKE_MFC_FLAG"><b><code>CMAKE_MFC_FLAG</code></b></a></li> <li><a href="#variable:CMAKE_MODULE_PATH"><b><code>CMAKE_MODULE_PATH</code></b></a></li> <li><a href="#variable:CMAKE_NOT_USING_CONFIG_FLAGS"><b><code>CMAKE_NOT_USING_CONFIG_FLAGS</code></b></a></li> <li><a href="#variable:CMAKE_POLICY_DEFAULT_CMPNNNN"><b><code>CMAKE_POLICY_DEFAULT_CMP<NNNN></code></b></a></li> <li><a href="#variable:CMAKE_PREFIX_PATH"><b><code>CMAKE_PREFIX_PATH</code></b></a></li> <li><a href="#variable:CMAKE_PROGRAM_PATH"><b><code>CMAKE_PROGRAM_PATH</code></b></a></li> <li><a href="#variable:CMAKE_SKIP_INSTALL_ALL_DEPENDENCY"><b><code>CMAKE_SKIP_INSTALL_ALL_DEPENDENCY</code></b></a></li> <li><a href="#variable:CMAKE_SYSTEM_IGNORE_PATH"><b><code>CMAKE_SYSTEM_IGNORE_PATH</code></b></a></li> <li><a href="#variable:CMAKE_SYSTEM_INCLUDE_PATH"><b><code>CMAKE_SYSTEM_INCLUDE_PATH</code></b></a></li> <li><a href="#variable:CMAKE_SYSTEM_LIBRARY_PATH"><b><code>CMAKE_SYSTEM_LIBRARY_PATH</code></b></a></li> <li><a href="#variable:CMAKE_SYSTEM_PREFIX_PATH"><b><code>CMAKE_SYSTEM_PREFIX_PATH</code></b></a></li> <li><a href="#variable:CMAKE_SYSTEM_PROGRAM_PATH"><b><code>CMAKE_SYSTEM_PROGRAM_PATH</code></b></a></li> <li><a href="#variable:CMAKE_USER_MAKE_RULES_OVERRIDE"><b><code>CMAKE_USER_MAKE_RULES_OVERRIDE</code></b></a></li> <li><a href="#variable:CMAKE_WARN_DEPRECATED"><b><code>CMAKE_WARN_DEPRECATED</code></b></a></li> <li><a href="#variable:CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION"><b><code>CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION</code></b></a></li> </ul> <ul> <li> <a name="variable:BUILD_SHARED_LIBS"></a><b><code>BUILD_SHARED_LIBS</code></b>: Global flag to cause add_library to create shared libraries if on.<br /> <p>If present and true, this will cause all libraries to be built shared unless the library was explicitly added as a static library. This variable is often added to projects as an OPTION so that each user of a project can decide if they want to build the project using shared or static libraries.</p> </li> <li> <a name="variable:CMAKE_ABSOLUTE_DESTINATION_FILES"></a><b><code>CMAKE_ABSOLUTE_DESTINATION_FILES</code></b>: List of files which have been installed using an ABSOLUTE DESTINATION path.<br /> <p>This variable is defined by CMake-generated cmake_install.cmake scripts. It can be used (read-only) by programs or scripts that source those install scripts. This is used by some CPack generators (e.g. RPM).</p> </li> <li> <a name="variable:CMAKE_AUTOMOC_RELAXED_MODE"></a><b><code>CMAKE_AUTOMOC_RELAXED_MODE</code></b>: Switch between strict and relaxed automoc mode.<br /> <p>By default, automoc behaves exactly as described in the documentation of the AUTOMOC target property. When set to TRUE, it accepts more input and tries to find the correct input file for moc even if it differs from the documented behaviour. In this mode it e.g. also checks whether a header file is intended to be processed by moc when a "foo.moc" file has been included.<br /></p> <p>Relaxed mode has to be enabled for KDE4 compatibility.</p> </li> <li> <a name="variable:CMAKE_BACKWARDS_COMPATIBILITY"></a><b><code>CMAKE_BACKWARDS_COMPATIBILITY</code></b>: Version of cmake required to build project<br /> <p>From the point of view of backwards compatibility, this specifies what version of CMake should be supported. By default this value is the version number of CMake that you are running. You can set this to an older version of CMake to support deprecated commands of CMake in projects that were written to use older versions of CMake. This can be set by the user or set at the beginning of a CMakeLists file.</p> </li> <li> <a name="variable:CMAKE_BUILD_TYPE"></a><b><code>CMAKE_BUILD_TYPE</code></b>: Specifies the build type on single-configuration generators.<br /> <p>This statically specifies what build type (configuration) will be built in this build tree. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This variable is only meaningful to single-configuration generators (such as make and Ninja) i.e. those which choose a single configuration when CMake runs to generate a build tree as opposed to multi-configuration generators which offer selection of the build configuration within the generated build environment. There are many per-config properties and variables (usually following clean SOME_VAR_<CONFIG> order conventions), such as CMAKE_C_FLAGS_<CONFIG>, specified as uppercase: CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL]. For example, in a build tree configured to build type Debug, CMake will see to having CMAKE_C_FLAGS_DEBUG settings get added to the CMAKE_C_FLAGS settings. See also CMAKE_CONFIGURATION_TYPES.</p> </li> <li> <a name="variable:CMAKE_COLOR_MAKEFILE"></a><b><code>CMAKE_COLOR_MAKEFILE</code></b>: Enables color output when using the Makefile generator.<br /> <p>When enabled, the generated Makefiles will produce colored output. Default is ON.</p> </li> <li> <a name="variable:CMAKE_CONFIGURATION_TYPES"></a><b><code>CMAKE_CONFIGURATION_TYPES</code></b>: Specifies the available build types on multi-config generators.<br /> <p>This specifies what build types (configurations) will be available such as Debug, Release, RelWithDebInfo etc. This has reasonable defaults on most platforms, but can be extended to provide other build types. See also CMAKE_BUILD_TYPE for details of managing configuration data, and CMAKE_CFG_INTDIR.</p> </li> <li> <a name="variable:CMAKE_DEBUG_TARGET_PROPERTIES"></a><b><code>CMAKE_DEBUG_TARGET_PROPERTIES</code></b>: Enables tracing output for target properties.<br /> <p>This variable can be populated with a list of properties to generate debug output for when evaluating target properties. Currently it can only be used when evaluating the INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS and COMPILE_OPTIONS target properties. In that case, it outputs a backtrace for each entry in the target property. Default is unset.</p> </li> <li> <a name="variable:CMAKE_DISABLE_FIND_PACKAGE_PackageName"></a><b><code>CMAKE_DISABLE_FIND_PACKAGE_<PackageName></code></b>: Variable for disabling find_package() calls.<br /> <p>Every non-REQUIRED find_package() call in a project can be disabled by setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE. This can be used to build a project without an optional package, although that package is installed.<br /></p> <p>This switch should be used during the initial CMake run. Otherwise if the package has already been found in a previous CMake run, the variables which have been stored in the cache will still be there. In that case it is recommended to remove the cache variables for this package from the cache using the cache editor or cmake -U</p> </li> <li> <a name="variable:CMAKE_ERROR_DEPRECATED"></a><b><code>CMAKE_ERROR_DEPRECATED</code></b>: Whether to issue deprecation errors for macros and functions.<br /> <p>If TRUE, this can be used by macros and functions to issue fatal errors when deprecated macros or functions are used. This variable is FALSE by default.</p> </li> <li> <a name="variable:CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION"></a><b><code>CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION</code></b>: Ask cmake_install.cmake script to error out as soon as a file with absolute INSTALL DESTINATION is encountered.<br /> <p>The fatal error is emitted before the installation of the offending file takes place. This variable is used by CMake-generated cmake_install.cmake scripts. If one sets this variable to ON while running the script, it may get fatal error messages from the script.</p> </li> <li> <a name="variable:CMAKE_FIND_LIBRARY_PREFIXES"></a><b><code>CMAKE_FIND_LIBRARY_PREFIXES</code></b>: Prefixes to prepend when looking for libraries.<br /> <p>This specifies what prefixes to add to library names when the find_library command looks for libraries. On UNIX systems this is typically lib, meaning that when trying to find the foo library it will look for libfoo.</p> </li> <li> <a name="variable:CMAKE_FIND_LIBRARY_SUFFIXES"></a><b><code>CMAKE_FIND_LIBRARY_SUFFIXES</code></b>: Suffixes to append when looking for libraries.<br /> <p>This specifies what suffixes to add to library names when the find_library command looks for libraries. On Windows systems this is typically .lib and .dll, meaning that when trying to find the foo library it will look for foo.dll etc.</p> </li> <li> <a name="variable:CMAKE_FIND_PACKAGE_WARN_NO_MODULE"></a><b><code>CMAKE_FIND_PACKAGE_WARN_NO_MODULE</code></b>: Tell find_package to warn if called without an explicit mode.<br /> <p>If find_package is called without an explicit mode option (MODULE, CONFIG or NO_MODULE) and no Find<pkg>.cmake module is in CMAKE_MODULE_PATH then CMake implicitly assumes that the caller intends to search for a package configuration file. If no package configuration file is found then the wording of the failure message must account for both the case that the package is really missing and the case that the project has a bug and failed to provide the intended Find module. If instead the caller specifies an explicit mode option then the failure message can be more specific.<br /></p> <p>Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package to warn when it implicitly assumes Config mode. This helps developers enforce use of an explicit mode in all calls to find_package within a project.</p> </li> <li> <a name="variable:CMAKE_IGNORE_PATH"></a><b><code>CMAKE_IGNORE_PATH</code></b>: Path to be ignored by FIND_XXX() commands.<br /> <p>Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in cross-compiled environments where some system directories contain incompatible but possibly linkable libraries. For example, on cross-compiled cluster environments, this allows a user to ignore directories containing libraries meant for the front-end machine that modules like FindX11 (and others) would normally search. By default this is empty; it is intended to be set by the project. Note that CMAKE_IGNORE_PATH takes a list of directory names, NOT a list of prefixes. If you want to ignore paths under prefixes (bin, include, lib, etc.), you'll need to specify them explicitly. See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.</p> </li> <li> <a name="variable:CMAKE_INCLUDE_PATH"></a><b><code>CMAKE_INCLUDE_PATH</code></b>: Path used for searching by FIND_FILE() and FIND_PATH().<br /> <p>Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained directories for the existence of the file which is currently searched. By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.</p> </li> <li> <a name="variable:CMAKE_INSTALL_DEFAULT_COMPONENT_NAME"></a><b><code>CMAKE_INSTALL_DEFAULT_COMPONENT_NAME</code></b>: Default component used in install() commands.<br /> <p>If an install() command is used without the COMPONENT argument, these files will be grouped into a default component. The name of this default install component will be taken from this variable. It defaults to "Unspecified".</p> </li> <li> <a name="variable:CMAKE_INSTALL_PREFIX"></a><b><code>CMAKE_INSTALL_PREFIX</code></b>: Install directory used by install.<br /> <p>If "make install" is invoked or INSTALL is built, this directory is prepended onto all install directories. This variable defaults to /usr/local on UNIX and c:/Program Files on Windows.<br /></p> <p>On UNIX one can use the DESTDIR mechanism in order to relocate the whole installation. DESTDIR means DESTination DIRectory. It is commonly used by makefile users in order to install software at non-default location. It is usually invoked like this:<br /></p> <pre> make DESTDIR=/home/john install<br /></pre> <p>which will install the concerned software using the installation prefix, e.g. "/usr/local" prepended with the DESTDIR value which finally gives "/home/john/usr/local".<br /></p> <p>WARNING: DESTDIR may not be used on Windows because installation prefix usually contains a drive letter like in "C:/Program Files" which cannot be prepended with some other prefix.<br /></p> <p>The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so that find_package, find_program, find_library, find_path, and find_file will search the prefix for other software.</p> </li> <li> <a name="variable:CMAKE_LIBRARY_PATH"></a><b><code>CMAKE_LIBRARY_PATH</code></b>: Path used for searching by FIND_LIBRARY().<br /> <p>Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the contained directories for the existence of the library which is currently searched. By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.</p> </li> <li> <a name="variable:CMAKE_MFC_FLAG"></a><b><code>CMAKE_MFC_FLAG</code></b>: Tell cmake to use MFC for an executable or dll.<br /> <p>This can be set in a CMakeLists.txt file and will enable MFC in the application. It should be set to 1 for the static MFC library, and 2 for the shared MFC library. This is used in Visual Studio 6 and 7 project files. The CMakeSetup dialog used MFC and the CMakeLists.txt looks like this:<br /></p> <pre> add_definitions(-D_AFXDLL)<br /> set(CMAKE_MFC_FLAG 2)<br /> add_executable(CMakeSetup WIN32 ${SRCS})<br /></pre> </li> <li> <a name="variable:CMAKE_MODULE_PATH"></a><b><code>CMAKE_MODULE_PATH</code></b>: List of directories to search for CMake modules.<br /> <p>Commands like include() and find_package() search for files in directories listed by this variable before checking the default modules that come with CMake.</p> </li> <li> <a name="variable:CMAKE_NOT_USING_CONFIG_FLAGS"></a><b><code>CMAKE_NOT_USING_CONFIG_FLAGS</code></b>: Skip _BUILD_TYPE flags if true.<br /> <p>This is an internal flag used by the generators in CMake to tell CMake to skip the _BUILD_TYPE flags.</p> </li> <li> <a name="variable:CMAKE_POLICY_DEFAULT_CMPNNNN"></a><b><code>CMAKE_POLICY_DEFAULT_CMP<NNNN></code></b>: Default for CMake Policy CMP<NNNN> when it is otherwise left unset.<br /> <p>Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by default leave policies introduced after the given version unset. Set CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to specify the default for policy CMP<NNNN>, where <NNNN> is the policy number.<br /></p> <p>This variable should not be set by a project in CMake code; use cmake_policy(SET) instead. Users running CMake may set this variable in the cache (e.g. -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set a policy not otherwise set by the project. Set to OLD to quiet a policy warning while using old behavior or to NEW to try building the project with new behavior.</p> </li> <li> <a name="variable:CMAKE_PREFIX_PATH"></a><b><code>CMAKE_PREFIX_PATH</code></b>: Path used for searching by FIND_XXX(), with appropriate suffixes added.<br /> <p>Specifies a path which will be used by the FIND_XXX() commands. It contains the "base" directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.</p> </li> <li> <a name="variable:CMAKE_PROGRAM_PATH"></a><b><code>CMAKE_PROGRAM_PATH</code></b>: Path used for searching by FIND_PROGRAM().<br /> <p>Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the contained directories for the existence of the program which is currently searched. By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.</p> </li> <li> <a name="variable:CMAKE_SKIP_INSTALL_ALL_DEPENDENCY"></a><b><code>CMAKE_SKIP_INSTALL_ALL_DEPENDENCY</code></b>: Don't make the install target depend on the all target.<br /> <p>By default, the "install" target depends on the "all" target. This has the effect, that when "make install" is invoked or INSTALL is built, first the "all" target is built, then the installation starts. If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency is not created, so the installation process will start immediately, independent from whether the project has been completely built or not.</p> </li> <li> <a name="variable:CMAKE_SYSTEM_IGNORE_PATH"></a><b><code>CMAKE_SYSTEM_IGNORE_PATH</code></b>: Path to be ignored by FIND_XXX() commands.<br /> <p>Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in cross-compiled environments where some system directories contain incompatible but possibly linkable libraries. For example, on cross-compiled cluster environments, this allows a user to ignore directories containing libraries meant for the front-end machine that modules like FindX11 (and others) would normally search. By default this contains a list of directories containing incompatible binaries for the host system. See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.</p> </li> <li> <a name="variable:CMAKE_SYSTEM_INCLUDE_PATH"></a><b><code>CMAKE_SYSTEM_INCLUDE_PATH</code></b>: Path used for searching by FIND_FILE() and FIND_PATH().<br /> <p>Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained directories for the existence of the file which is currently searched. By default it contains the standard directories for the current system. It is NOT intended to be modified by the project, use CMAKE_INCLUDE_PATH for this.

So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default this contains the standard directories for the current system and the CMAKE_INSTALL_PREFIX. It is NOT intended to be modified by the project, use CMAKE_PREFIX_PATH for this.

It is loaded after CMake's builtin compiler and platform information modules have been loaded but before the information is used. The file may set platform information variables to override CMake's defaults.<br /></p> <p>This feature is intended for use only in overriding information variables that must be set before CMake builds its first test project to check that the compiler for a language works. It should not be used to load a file in cases that a normal include() will work. Use it only as a last resort for behavior that cannot be achieved any other way. For example, one may set CMAKE_C_FLAGS_INIT to change the default value used to initialize CMAKE_C_FLAGS before it is cached. The override file should NOT be used to set anything that could be set after languages are enabled, such as variables like CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of binaries.

Example values:<br /></p> <pre> $(IntDir) = Visual Studio 6<br /> $(OutDir) = Visual Studio 7, 8, 9<br /> $(Configuration) = Visual Studio 10<br /> $(CONFIGURATION) = Xcode<br /> . = Make-based tools<br /></pre> <p>Since these values are evaluated by the native build system, this variable is suitable only for use in command lines that will be evaluated at build time. Example of intended usage:<br /></p> <pre> add_executable(mytool mytool.c)<br /> add_custom_command(<br /> OUTPUT out.txt<br /> COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool<br /> ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt<br /> DEPENDS mytool in.txt<br /> )<br /> add_custom_target(drive ALL DEPENDS out.txt)<br /></pre> <p>Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but has been left for compatibility with existing projects. Instead add_custom_command() recognizes executable target names in its COMMAND option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool" can be replaced by just "mytool".<br /></p> <p>This variable is read-only. Setting it is undefined behavior. In multi-configuration build systems the value of this variable is passed as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation of all source files.</p> </li> <li> <a name="variable:CMAKE_COMMAND"></a><b><code>CMAKE_COMMAND</code></b>: The full path to the cmake executable.<br /> <p>This is the full path to the CMake executable cmake which is useful from custom commands that want to use the cmake -E option for portable system commands.

The value has dynamic scope. When CMake starts processing commands in a source file it sets this variable to the directory where this file is located. When CMake finishes processing commands from the file it restores the previous value. Therefore the value of the variable inside a macro or function is the directory of the file invoking the bottom-most entry on the call stack, not the directory of the file containing the macro or function definition.<br /></p> <p>See also CMAKE_CURRENT_LIST_FILE.</p> </li> <li> <a name="variable:CMAKE_CURRENT_LIST_FILE"></a><b><code>CMAKE_CURRENT_LIST_FILE</code></b>: Full path to the listfile currently being processed.<br /> <p>As CMake processes the listfiles in your project this variable will always be set to the one currently being processed.
