When we look at CMakeLists.txt into kde project we can see that all program 
have a automoc (I didn't see a lot of cmakelists.txt which have not a automoc 
=> for me it will better to use a NO_AUTOMOC argument to disable it.

I don't like it, because we must set/unset variable, and it's easy to forgot 
to unset it into same CMakeLists.txt
