Modified fork of ndsmusicplayer/vio2play that uses libao so you don't have to mess around with aoss or padsp (and use them on platforms where OSS doesn't exist at all). Additionally uses CMake because I decided to.

Only external dependency is libao (plus whatever additional dependencies are required on your platform for the default driver). Build in the usual CMake way (mkdir build && cd build && cmake .. && make).

By way of being a derivative work of DeSmuME this program is licensed under GPLv2. In addition, the FindLibAO CMake module was cribbed from the iola non-linear video editor which is also GPLv2 licensed.

Please note this is a quick hack and you're on your own if it doesn't work.

Tested to work on Linux x86_64 and macOS. Probably won't work on Windows as it still uses some POSIX calls.
