[CMake] enable_language( ... OPTIONAL) causes error or second cmake run

[Marcel Loose]

Hi Alex,

Maybe I'm overlooking all kinds of side effects, but the problem is in
line 6 of CMakeFortranInformation.cmake, where get_filename_component()
is called with an incorrect number of arguments. This happens because
${CMAKE_Fortran_COMPILER} is empty. If I simply put quotes around
${CMAKE_Fortran_COMPILER} the problem is solved. Or so it seems. Right,
or wrong?

Best regards,
Marcel Loose.
