| 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. |
