It's far from perfect but it should now be easier to build MuseScore on OSX
with homebrew. I used the pkg-config code Marc provided and added if else
to deal with platform differences and build options. The Lame issue is
solved in a CMake module. Tests are welcome.
I also tried the LLVM bug trick by building my own vorbis lib, but it's not
the cause of the crash... So I'm again clueless. If anyone has an idea why
MuseScore crashes on startup while loading fluid.sf3, apparently
in decompressOggVorbis, shoot!
