I’m having a difficult time using opencv with cinder on an apple silicon computer. I’m using cinder 0.9.3, a 2023 M2 Pro Macbook Pro, Ventura 13.6.2, Xcode 15.2, and the Cinder-OpenCV3 block. It’s skipping over the opencv files because they aren’t arm64, but x86\_64. Any help would be greatly appreciated!

I also get these with no explanation:

```auto
Undefined symbols:

Linker command failed with exit code 1 (use -v to see invocation)

```

I tried using the openframeworks opencv library and I don’t get the skips for arm64 anymore, but I do get this linker error if I call any opencv function.

Ahh, got the linker issue sorted out, it was still trying to link the cinder block files instead of the oF files. The openFrameworks version is working (so far).

Would be great to get the cinder block updated for arm64. I can do it and make a pull request if someone wants to give me some guidance.
