Ah, ok. 
The generated moc file is included in one of the source files. Since 
cmake doesn't "see" this, it complains about it. 
I have the same effect for an external library which is created and 
linked to directly via a customized CMAKE_CXX_LINK_EXECUTABLE, so here 
cmake also doesn't know that it's used. 
Can I switch this warning off ?
