This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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 CMAKE_Fortran_COMPILER. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_Fortran_COMPILER variable is defined.
