Updated CMake files for QTEditor cmake style.

AudioOutput had previously stalled, mutex temporary removed(Q&D workaround, need for study OSX Audio Concurency).
Removed some part of code in DemodBFM for OSX compilations.
Code runs and was tested with HackRF.
Note: There is need have investigate two potencial problems(DemodBFM bug and AudioOutput deadlocking?).
