Compile without audio

[xaratustrah]

If audio is not needed, I was wondering if it is possible to compile gqrx without audio support? Maybe similar to #258 (comment) by passing an argument to cmake but this time in order to turn off all audio dependencies / features?

I did the cmake approach, see here:

Thanks. I just cloned your version from here, in the build directory I run::

cmake -DLINUX_AUDIO_BACKEND=Null-audio ..

I still get:

CMake Error at CMakeLists.txt:198 (message):
  Invalid audio backend: should be either Pulseaudio, Portaudio, Null-audio,
  or Gr-audio

maybe I should invoke it differently?

I implemented this only for Darwin (macos).
I tried to fix it, but I cannot currently test it.

Please pull and try again.

PS: my fork has many other changes vs. master , maybe you should try to just apply that commit to master
