amarok - postgres support

I asked this question many months ago, over on the 'users' list but never got an answer, so here goes; How do I get postgres support compiled into amarok (assuming said support hasn't been removed) when building from the latest GIT source, which uses cmake? There don't appear to be any clues in the CMakeLists.txt files. In the good old days it was as simple as '--enable-postgres'. Of course, I could be missing something obvious :) Cheers, Mike. -- Any question is easy if you know the answer!
