FC

.. include:: include/ENV_VAR.rst

Preferred executable for compiling Fortran language files. Will only be used by CMake on the first configuration to determine Fortran compiler, after which the value for Fortran is stored in the cache as :variable:CMAKE_Fortran_COMPILER <CMAKE_<LANG>_COMPILER>. For any configuration run (including the first), the environment variable will be ignored if the :variable:CMAKE_Fortran_COMPILER <CMAKE_<LANG>_COMPILER> variable is defined.

.. note:: Options that are required to make the compiler work correctly can be included; they can not be changed.

.. code-block:: console
