Compilation on arm

Hi,
I’m trying to compile cocos2d-x 3.0rc1 on a Raspberry Pi. I’m stuck during the process because of the external library FMOD for audio which is not built for armv6. What I’d like to do is use OpenAL as an alternative. I need to know the way to exclude, in some CMake options, FMOD and enable OpenAL for the SimpleAudioEngine.

I really need cocos built for RPi, so if there is some other known way to do it, it’s even better.

Thanks to all
Francesco
