Changes in v2.7.1:
Fixed ticket #45: the sonivox library dependency (for the SonivoxEAS synth backend) is optional, and easily forgotten by 3rd party packagers. The build system configuration now fails with an error message if the sonivox library is missing unless the cmake variables USE_SONIVOX and USE_PULSEAUDIO are set to OFF. Same failure with the FluidSynth backend and the variable USE_FLUIDSYNTH, and the ipMIDI Network backend and USE_NETWORK.

Changes in v2.7.0:
ticket #44: removed sonivox library sources from the source tree. New option USE_SONIVOX to let the user decide to build the sonivox eas synth plugin or not.
