CheckFortranCompilerFlag
------------------------
.. versionadded:: 3.3
Check whether the Fortran compiler supports a given flag.
.. command:: check_fortran_compiler_flag
.. code-block:: cmake
check_fortran_compiler_flag(<flag> <resultVar>)
Check that the ``<flag>`` is accepted by the compiler without
a diagnostic. Stores the result in an internal cache entry
named ``<resultVar>``.
A positive result from this check indicates only that the compiler did not
issue a diagnostic message when given the flag. Whether the flag has any
effect or even a specific one is beyond the scope of this module.
The check is only performed once, with the result cached in the variable named
by ``<resultVar>``. Every subsequent CMake run will re-use this cached value
rather than performing the check again, even if the ``<code>`` changes. In
order to force the check to be re-evaluated, the variable named by
``<resultVar>`` must be manually removed from the cache.
The compile and link commands can be influenced by setting any of the
following variables prior to calling ``check_fortran_compiler_flag()``

.. include:: /module/CMAKE_REQUIRED_DEFINITIONS.txt
