Can't build on macOS Monterey

[fredguth]

I wasn't able to just cargo build the project in macOS Monterey.

The error:

Compiling coreaudio-sys v0.2.2
error: failed to run custom build command for `coreaudio-sys v0.2.2`

Caused by:
  process didn't exit successfully: `/Users/fredguth/Code/pianocast/experiments/synthesizer-io/target/debug/build/coreaudio-sys-a05d30c9e3820cb9/build-script-build` (exit status: 101)

I guess the problem is that CoreMIDI.framework path is hard coded. Because in my machine it is intalled inside Xcode.app contents:

xcrun --sdk macosx --show-sdk-path 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.3.sdk
