- define a base image (close to the image used in the old CI, but based on the LTS).
- define a product which will group all relevant Qt4 programs.
The available dependencies should be enough to compile at least
qca, phonon, phonon-vlc, phonon-gstreamer, soprano, kdelibs,
nepomuk-core (reduced dependencies), nepomuk-widgets, kactivities,
akonadi, kdepimlibs, kde-runtime, libkdegames and few applications.
