Summary:                    if( languages MATCHES c) always true for pure
Fortran projects
Description: 
A lot of Modules (for example findBLAS.cmake, findLAPACK.cmake) do checks of the
form:

get_property( _LANGUAGES_ GLOBAL PROPERTY ENABLED_LANGUAGES )
if( _LANGUAGES_ MATCHES C )
...

Even in pure Fortran projects this is always true on windows systems as the RC
language is added automatically (and Fortran;RC MATCHES C).

Steps to Reproduce: 
Create a pure Fortran project and call find_package(LAPACK).
