Hey all, I'm trying to build the develop branch on an M1 mac and
totally failing. I tried using libsndfile from homebrew but the csound
link says it can't use it because it's arm64 only, and the csound
build wants a universal binary? Is that right?

How do I do this?

I would expect that CMake won't try and build a universal binary if you don't ask. Anyway, you can use CMAKE_OSX_ARCHITECTURE=arm64 
and I think it should force the build to be a single architecture.

Also make sure you have a fresh build directory.

Ah, yes! I had forgotten about the Custom.cmake I was using a few
months back. Deleting that fixed the build issues. Thanks!
