Great.

I'm surprised that you say that these worked before:
   Qt5, Phonon 4 on Qt4*
   Qt5, Phonon 5 on Qt4*
With the code in the toplevel CMakeLists.txt, there was no way to use any phonon in KF5+Qt5. So I'm glad this is going in, so that all the code can be compiled with Qt5 (until now my qt5-build didn't build everything that my qt4-build was building).



interfaces/CMakeLists.txt
<http://git.reviewboard.kde.org/r/106987/#comment17184>

    Shouldn't the find_package(Phonon) be done before this line, rather than inside interfaces/kmediaplayer?
    
    I'm not sure yet how we'll split up this directory, to be honest. But since the toplevel kdelibs goes away for sure, a find_package is definitely needed here.



knotify/config/CMakeLists.txt
<http://git.reviewboard.kde.org/r/106987/#comment17183>

    This seems to use the wrong variable, and too early (before the find_package(Phonon) that you added below.



knotify/config/CMakeLists.txt
<http://git.reviewboard.kde.org/r/106987/#comment17182>

    This will lead to compiler warnings/errors when phonon isn't found, because #if HAVE_PHONON will say "not defined!".
    
    The proper way to do this is a configure_file for a knotify-config.h, with #cmakedefine01 in the knotify-config.h.cmake, like in many other places in kdelibs.
    
    Or maybe Phonon is just required for this code.
