gcompris-qt doesn't works well. Two libs are missing (at least) x11-toolkits/qt5-quickcontrols and graphics/qt5-graphicaleffects. After that, some games are unusable (missing graphics). I'll try deeper tests later
So, just add these libs x11-toolkits/qt5-quickcontrols and graphics/qt5-graphicaleffects and it will works after a restart
