Raw Rust bindings for RtAudio.
This is used by the rtaudio crate, which provides a safe wrapper with a more Rust-y API.
Bindings are auto-generated using bindgen from the official C header. No bindings to the C++ interface are provided.
This will build RtAudio from source. Don't forget to initialize git submodules (git submodule update --init) or clone with --recursive.
