Each build system is different. I don't know how freecad's build system expects additional flags to be specified.

Ideally, the build system would not require you to specify that. The developers may be able to fix it by including the output of "$CMAKE_Fortran_COMPILER -print-file-name=libgfortran.dylib" at the right place.
