Bug Description

I discovered the problem when I tried to compile a Qt5 QML program firstly.

I have an Ubuntu 14.04.2 LTS with all updates, no significant PPAs (only nodejs and owncloud, not affecting this problem here) and with all the -lts-utopic upgrade packages installed.

With that system, I tried to install qtbase5-dev, and apt told me:

[...]

The following packages have unmet dependencies:

qtbase5-dev : Depends: libgles2-mesa-dev or

libgles2- dev but it is not installable

unity- control- center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed

Depends: libcheese7 (>= 3.0.1) but it is not going to be installed

E: Error, pkgProblemResol ver::Resolve generated breaks, this may be caused by held packages.

So this package seems to be not installable. This tried in synaptic, it tries to uninstall all -lts-utopic packages (inclusive all xserver*.deb) and install the "old" ones instead of them.

So the problem somewhere lies within the new lts packages that seem not to be compatible with qtbase5-dev (and its dependency: libgles2-mesa-dev - but I am not able to find out further.

The problem is: Qt5 development on an Ubuntu 14.04.2 LTS machine is NOT possible without a fix. The make process always complains about not finding gl libraries.
