Can you manually set the ADDITIONAL_MAKE_CLEAN_FILES directory property to 
some file and check whether this file is deleted when you clean ?

Something like

set_directory_properties(PROPERTIES ADDITIONAL_MAKE_CLEAN_FILES
                                    "${CMAKE_CURRENT_BINARY_DIR}/abc.txt" )
 

then just create such a file in the build dir, and clean.
It should be removed then.
If it is not, then this is the reason why clean doesn't clean automoc 
properly.
