OK, you are going to have to look at the C++ code to figure this out.

You will need to add some debug prints to this function:

void
cmGlobalGenerator::EnableLanguage(std::vector<std::string>const& languages,
                                   cmMakefile *mf, bool)

...

   for(std::vector<std::string>::const_iterator l = languages.begin();
       l != languages.end(); ++l)
     {

Seems that Fortran is getting into the list of enabled languages.

Might also want to put prints in cmEnableLanguageCommand
::InitialPass  and void 
cmMakefile::EnableLanguage(std::vector<std::string> const &  lang,
                                bool optional)
