Alright, I see that the extra-target version is faster at make time. Since 
with cmake 2.6 running cmake is faster already there goes anther argument. My 
last argument for custom_command is that make target/fast would run automoc, 
but this can be helped by a little helper script that turns "make foo/fast" 
into "make foo_automoc/fast foo/fast"...

I'll come up with a patch to keep compatibility where possible but switch to 
automoc targets when possible.

Yes.

When you call make -j5 then it can happen that you get 5 concurrently running 
automoc4 processes. The extra parallelization inside automoc4 isn't really 
necessary and for unexplainable reasons broke on FreeBSD and some other 
platforms.
