Sorry, forgot to update the .pro file.
The cmake build system scans the directories, so no need to update any file.
Seems this is worth to be mentioned in the INSTALL file.

"Aucun fichier ou dossier de ce type" what does this mean? "Could not find"?

Strange, I've tested it on Linux with 4.7 and 4.4, on Mac with 4.7, and on Windows with 4.7 and
never got an error because of qrc_images.cpp. What is your setup, Qt version, cmake version, Linux?
Do you have enough disk space?

Yes, sometimes it decides between waiting in front of the computer until the build is ready
or to leave it and to come back later.

I also have to document a feature of the merged build:
When you heavily work on one file you could comment out the relevant define in the
merged_const.cpp file, so only the file merged_touched.cpp file will be re-compiled again an again.
