Well, it's not that obviously.
Basically cmake did exactly what it was told to do, all files it generates are 
generated in CMAKE_CURRENT_BINARY_DIR.
Are you building in-source or out-of-source ?
Once you get used to it, out-of-source is much more convenient.

Which problem does this cause for you ?

If you have the problem that there are now two generated files with the same 
name, you have hit the leftovers from libtool and the convenience libs. 
Now all source files are just compiled at once for one target. So if you have 
in different subdirs files with the same name, the generated moc files will 
have the same name. Even if they would be generated in different directories 
(which they are not currently), this wouldn't help anything.
In order to find them, the path to them would have to be part of the include 
path. Which would mean the path to both files with the same name would be in 
the include path, and that for both files. Which would have the effect that 
both times when e.g. foo.moc gets included the same foo.moc would be 
included.

Are you building in-source or out-of-source ?
Once you get used to it, out-of-source is much more convenient. And when 
building out-of-source, the moc files have to be found via the include path, 
because they live in the build tree, while the source files including them 
live in the source tree.

So, what is the exact problem ? Maybe it's just a missing path in the include 
path ?
