It does not just scan all *.h files, it only looks for headers which seem to 
belong to a cpp file (i.e. for a foo.h if there is a foo.cpp in the target).

Multiple options are checked, *.h, *.hpp, *.hxx


You are right, this is guessing, and I don't like it.
But this is what automoc has been doing all the time since autotools time, so 
it has to be this way to be compatible.

I would prefer if it would not search for header files, but only use those 
header files which are listed as part of the sources for the target.

But this means you have to edit your cmake files if you add a Q_OBJECT in a 
header, and this was not wanted for KDE developers.

But we may be able to change this for Qt5.
