Hey! I am currently using this crate and it is working great :)
Unfortunately I can't cross compile on macos to the target "x86_64-apple-darwin" because the portaudio build can not find the MacOS SDK in that case.
x portaudio/install-sh
configure: error: Couldn't find 10.5, 10.6, 10.7, 10.8 or 10.9 SDK
Do you have any idea if there is a solution by just setting an environment variable or if that is a more complicated issue?
