OK, now I'm a bit stuck...
Tried to compile fcamera but qmake could not be executed. I thought that it could be that all build-deps are cssu so installing cssu could be the next step but it could not be installed because to install cssu enabler I have to verify something that needs the screen which is not available from chroot...

So I tried to compile libglib but dpkg-buildpackage stops and says there is no debian/changelog (which is true... at least with the source I downloaded).
