do we want to keep the out-of-source-only requirement ?

I think that when Joe Random Developer is doing an in-source build and
has a problem he/she is more likely to 'rm -rf' the whole tree and
redownload it via 'svn co' rather than 'svn-clean' it. The problem of
the cmake generated files hanging around and mucking up cmake
configuration also keeps rearing its head.

Both of these things may occur less if we allow only out-of-source
builds. AND we won't need to constantly worry about one or the other
breaking.
