So cmake 2.4.3 ?

I had a quick look at the sources.
Neither Job.cpp nor Thread.cpp are listed as a source file for the library.
Why ?
And the generated Job_moc.cpp and Thread_moc.cpp include Job.moc and 
Thread.moc ?
Job_moc.cpp and Thread_moc.cpp do not exist yet at cmake time, so if these 
generated files will include Thread.moc/Job.moc this cannot be detected at 
this time.

I don't really understand how the logic behind this.
Can you please explain ?

Bye
Alex
