it would be great if it can be installed with the package manager similar to opencv or have the binaries as a release.

this shouldnt be that difficult.
linux would probably need to run in a container: ubuntu:20.04 because glibc and these 2 runners could be added for unpopular OSes runs-on: ubuntu-24.04-arm,runs-on: macos-13, but it should be quite posible with slight tweaking of the build ci.
