I wouldn't say so.
automocing in general, while convinient, is kind of ugly.
If you do it with cmake macros, then changes are only detected at cmake time.
But cmake doesn't necessarily run if you change only a cpp file. That's the
first issue. Second, it becomes a lot of parsing work, and I think this is a
bit much work for a cmake script.
I'd really recommend to either do the mocing explicitely using the
QT_WRAP_CPP() macros etc., or be happy with the limited options of the
qt4_automoc() macro, or use automoc4:
