Bug#943870: auralquiz: FTBFS: undefined reference to `Phonon::phononVersion()'

Version: 1.0.0-2
Severity: serious

Dear maintainers,

I noticed that the auralquiz package has been failing to build in Ubuntu. 
Testing in Debian unstable shows that it fails to build the same way:

[...]
g++ -Wl,-z,relro -Wl,-z,now -o auralquiz main.o auralwindow.o optionsdialog.o answerbox.o ranking.o musicanalyzer.o qrc_auralquiz.o moc_auralwindow.o moc_optionsdialog.o moc_answerbox.o moc_ranking.o moc_musicanalyzer.o   -ltag /usr/lib/x86_64-linux-gnu/libQt5Widgets.so /usr/lib/x86_64-linux-gnu/libQt5Gui.so /usr/lib/x86_64-linux-gnu/libQt5Core.so /usr/lib/x86_64-linux-gnu/libGL.so -lpthread   
/usr/bin/ld: auralwindow.o: in function `AuralWindow::showAbout()':
./src/auralwindow.cpp:1152: undefined reference to `Phonon::phononVersion()'
/usr/bin/ld: auralwindow.o: in function `AuralWindow::nextSongLoaded()':
./src/auralwindow.cpp:1343: undefined reference to `Phonon::MediaObject::play()'
/usr/bin/ld: ./src/auralwindow.cpp:1344: undefined reference to `Phonon::MediaObject::pause()'
/usr/bin/ld: auralwindow.o: in function `AuralWindow::playerStateChanged(Phonon::State, Phonon::State)':

The undefined references are clearly because the binary uses libphonon but
is not being linked against it.  I do not know why it is not linking against
libphonon.

Cheers,
