Well it starts building, but I'm getting an error:
cocos gen-libs -p android --app-abi armeabi-v7a
make: *** No rule to make target `/Users/piotr/Documents/pierdoly/cocos2d-x-3.14/external/tremolo/Tremolo/bitwise.c', needed by `obj/local/armeabi-v7a/objs/vorbisidec/Tremolo/bitwise.o'. Stop.

Error running command, return code: 2.
Error running command, return code: 14.
I though I have to add tremolo in prebuilt-mk, but it's missing.
The problem is I have cocos2d-x 3.14.1 with my own adjustments (new audioengine as well). I've found some new bug fixes in audio so I've replaced cocos/audio with the new one and now I'm stuck, because I cannot compile it I can't move to 3.15 yet due to my adjustments (I don't remember where I did them).
