Unable to build on OSX

[shaneday]

I'm trying to build av1an to run on an M2 Mac. I have the git repo cloned and when I run 'cargo build' it reports the following: (I've trimmed some unrelated warnings and the most of the massive cc command line. I can attach the log if needed)

Compiling av1an-core v0.4.1
[...](error: linking with `cc` failed: exit status: 1)
= note: ld: library 'vapoursynth' not found
... "cc" "-arch" "arm64" ... "/Users/shaneday/git/av1an/target/debug/deps/libvapoursynth-2fbdbd40c09d3a15.rlib" ... "/Users/shaneday/git/av1an/target/debug/deps/libvapoursynth_sys-314baf9d1a70c691.rlib" 
... "-lvapoursynth" "-lvapoursynth-script" ...

I've installed vapoursynth using 'brew install vapoursynth' and I can see the vapoursynth library files:

❯ ls /opt/homebrew/lib/libvapoursynth*
/opt/homebrew/lib/libvapoursynth-script.0.dylib
/opt/homebrew/lib/libvapoursynth-script.a
/opt/homebrew/lib/libvapoursynth-script.dylib
/opt/homebrew/lib/libvapoursynth.a
/opt/homebrew/lib/libvapoursynth.dylib

I have tried following ChatGPTs advice and adding to Cargo.toml:

[build]
rustflags = ["-L/opt/homebrew/lib"]

and also tried:

CARGO_LINKFLAGS="-L/opt/homebrew/lib" cargo build

without any luck.

Some guidance would be appreciated. I'm familiar with the command line and C programming, but I've never touched rust or cargo.

I figure I'll drop the 'CARGO_LINKFLAGS="-L/opt/homebrew/lib" cargo build' log here just in case it is needed.

same issue, same platform, on macOS 14.4.1, same error and same log output references missing vapoursynth library
