See it this way: GNUInstallDirs.cmake contains the install dirs used and 
recommended by GNU (applications), KDEInstallDirs.cmake contains the install 
dirs used and recommended by KDE (applications).

So, whoever is fine with the subset what is in GNUInstallDirs.cmake, can use 
that, who needs more, can use KDEInstallDirs.cmake.

I mean, "kde" is a well-known name, we should not hide it.
