FindOpenACC
-----------

Detect OpenACC support by the compiler.

This module can be used to detect OpenACC support in a compiler.
If the compiler supports OpenACC, the flags required to compile with
OpenACC support are returned in variables for the different languages.
Currently, only PGI, GNU and Cray compilers are supported.

Variables
^^^^^^^^^

This module will set the following variables per language in your
project, where ``<lang>`` is one of C, CXX, or Fortran:

``OpenACC_<lang>_FOUND``
  Variable indicating if OpenACC support for ``<lang>`` was detected.
``OpenACC_<lang>_FLAGS``
  OpenACC compiler flags for ``<lang>``, separated by spaces.
``OpenACC_<lang>_OPTIONS``
  OpenACC compiler flags for ``<lang>``, as a list. Suitable for usage
  with target_compile_options or target_link_options.

Additionally, the module provides :prop_tgt:`IMPORTED` targets:

``OpenACC::OpenACC_<lang>``
  Target for using OpenACC from ``<lang>``.

The module will also try to provide the OpenACC version variables:

``OpenACC_<lang>_SPEC_DATE``
  Date of the OpenACC specification implemented by the ``<lang>`` compiler.
``OpenACC_<lang>_VERSION_MAJOR``
  Major version of OpenACC implemented by the ``<lang>`` compiler.
``OpenACC_<lang>_VERSION_MINOR``
  Minor version of OpenACC implemented by the ``<lang>`` compiler.
``OpenACC_<lang>_VERSION``
  OpenACC version implemented by the ``<lang>`` compiler.

The specification date is formatted as given in the OpenACC standard:
``yyyymm`` where ``yyyy`` and ``mm`` represents the year and month of
the OpenACC specification implemented by the ``<lang>`` compiler.

Input Variables
^^^^^^^^^^^^^^^

``OpenACC_ACCEL_TARGET=<target>``
If set, will the correct target accelerator flag set to the <target> will
be returned with OpenACC_<lang>_FLAGS.
