Setup for OSX, iOS, and Windows.
(docs coming? It's pretty easy to use, just include AudioManagerFMOD.cpp and link to the FMOD libs for your platform)
I got this error when targeting iOS 3.X using xCode 4.X. To fix, add -weak_library /usr/lib/libSystem.B.dylib this to the Other Linker Flags option in the project build settings.
