I'm strongly against enabling in-source cmake builds. Apart from being
IMHO bad practise
certain parts of our CMake files may be assuming. the build is out of
source (e.g. I had a patch recently that assumed this because
in-source builds were impossible at the time).

We seemed to be doing fine so far without in-source cmake builds so I
see no good reason to add support for them.
