According to Chris (the openal-soft developer) OSX comes with openal
support in its framework.
the problem is that the alut OSX has is quite old, so we'd need to do
some mac specific defines IIRC we alredy have mac defines here? maybe
this is done.

Otherwise if we want to use openal-soft with portaudio, on my linux
system portaudio is 180k/68k compressed so not too bad a dep.

Note - for static openal-soft use "set -DLIBTYPE=STATIC" with cmake,
its not documented :|
