How about the following:
- automoc, when done, writes an empty file <target>_automoc.notclean
- SET_DIRECTORY_PROPERTIES(PROPERTIES ADDITIONAL_MAKE_CLEAN_FILES 
<target>_automoc.notclean)
- automoc will recreate all moc files if the <target>_automoc.notclean file is 
not present (else it will work as it does now)

=>
after a make clean, running make which executes automoc will recreate all moc 
files.

This would again need automoc to be called unconditionally (which I still 
believe would be good to do - and the touch can be done by automoc itself, 
which would be portable).
