| 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. |
