Yes, works here :-) 
 
The following macro helps if you need to add deps from different places: 
 
MACRO(ADD_FILE_DEPENDANCY file) 
   SET(${file}_deps ${${file}_deps} ${ARGN}) 
   SET_SOURCE_FILES_PROPERTIES( ${file} 
      PROPERTIES OBJECT_DEPENDS "${${file}_deps}" ) 
ENDMACRO(ADD_FILE_DEPENDANCY) 
 
ADD_FILE_DEPENDANCY(foo.cpp test1.cpp test2.cpp) 
 
and somewhere else: 
 
ADD_FILE_DEPENDANCY(foo.cpp moc_foo.cpp) 
 
and then foo.cpp depends on all 3 files :-)
