[CMake] moc includes from source directory

[Craig Bradney]

Hi,

I'm wondering if theres an option or setting I have missed for outof source 
builds.

When you build Scribus out of source, and the source directory has been used 
for building in-source with autotools, the moc files from the source 
directory are used instead of cmake creating them in its own directories in 
the build dir.

Any ideas (apart from building autotools in another location)?

Regards
Craig
