We set CMAKE_Fortran_SIZEOF_DATA_PTR in the Fortran compiler information file after detecting the compiler ABI. However, since Fortran does not really have pointers, the preprocessor-based detection is unreliable. The result is needed to set CMAKE_SIZEOF_VOID_P only for Fortran-only projects because the value can come from C or C++ compilers otherwise. Therefore when CMAKE_SIZEOF_VOID_P is available from another language we should defer to it.
