[CMake] CMAKE_SOURCE_DIR overwritten by CMake Fortran language support

[Arjen Markus]

Hi Alan,

I have no time today to really dig into the output, but while
CMAKE_HOMEDIRECTORY points to the right directory, the outcome is
the same: the "wrong" information file gets loaded.

I will send the detailed output from cmake --trace in a separate
mail (> 0.5 MB).

Regards,

Arjen
