Well at least one of the developers are interested in the bug report I
filed.
I have now turned on verbose cmake files using the cmake-gui and have
compiled and posted the contents on the bug report.
He seems to think that it is not actually linking against the phonon
library. As there is only ONE phonon library that I have installed,
namely the updated one it appears to me that there has been a mixup in
their commits as the exact same thing is happening with their git version.
