Does it work if one is using qmake simply because phonon is in the linker's 
standard search paths?
Or does qmake on Ubuntu know how to find phonon?

phonon is treated as a Qt module as far as qmake and FindQt4.cmake are 
concerned, and not as a 3rd party library, like zlib and others.

But, I'm not opposed to modifying FindQt4.cmake, but I have a concern if one 
builds their own Qt (different version) without phonon, is it OK to find 
/usr/lib/libphonon.so?
