It seems that the bug is in KDE/Phonon. Why do they populate the 
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES instead of the INCLUDE_DIRECTORIES 
directory property? 

The patch that you added looks like a hack to me which is only for the 
benefit of what KDE/Phonon is doing (but maybe shouldn't be). I'd prefer to 
fix KDE/Phonon instead.

Thanks,

Steve.
