Thanks @roymacdonald for adding the config file.
The files in src/SoundObjects are not found. I get the following error message.
/Users/thomasgeissl/programming/of/openFrameworks/addons/ofxSoundObjects/example-soundPlayerObject/src/ofApp.h:5:10: fatal error: 'waveformDraw.h' file not found
#include "waveformDraw.h"
Should not they be added automatically to the header search paths?
