Yes, there is also a directory 'Phonon'.  However, that is not the 
default installation location for it.  By default, it is installed in:

	${PREFIX}/include/KDE/Phonon

The problem would appear to be that the CMake file for KDE do not look 
for this include file in its default location.  This would probably mean 
that some change was made to the: PhononConfig.cmake file.

But, now it works and I can no longer reproduce the problem.

Yes.  I don't know what it wasn't being found.
