This is not considered a good practice. The reason is that it requires
an explicit cmake invocation everytime you add or remove a new
project. This can be obvious for you (the person who creates the
project) but someone updating his svn working copy would not notice that
an explicit re-run of cmake is required.

OTOH, if the projects/ dir is some kind of "local playground" for LLVM
users, it wouldn't a serious problem, as the changes made there are not
intended to be committed to the svn server. But anyways you should
mention the requirement for the explicit cmake invocation on
projects/CMakeLists.txt or the on the LLVM CMake doc (or on both).
