CheckFortranFunctionExists
--------------------------
Check if a Fortran function exists.
.. command:: CHECK_FORTRAN_FUNCTION_EXISTS
.. code-block:: cmake
CHECK_FORTRAN_FUNCTION_EXISTS(<function> <result>)
where
``<function>``
the name of the Fortran function
``<result>``
variable to store the result; will be created as an internal cache variable.
.. note::
This command does not detect functions in Fortran modules. In general it is
recommended to use :module:`CheckSourceCompiles` instead to determine if a
Fortran function or subroutine is available.
The following variables may be set before calling this macro to modify
the way the check is run:
``CMAKE_REQUIRED_LINK_OPTIONS``
.. versionadded:: 3.14
A :ref:`;-list <CMake Language Lists>` of options to add to the link
command (see :command:`try_compile` for further details).
``CMAKE_REQUIRED_LIBRARIES``
A :ref:`;-list <CMake Language Lists>` of libraries to add to the link
command. These can be the name of system libraries or they can be
:ref:`Imported Targets <Imported Targets>` (see :command:`try_compile` for
further details).
