This seems to be the bug: conan-io/conan#9252 It seems to be generally applicable for cross-compiling with auto tools. However, it might be also related to us not using the --profile:build/--profile:host feature of Conan, or have you tried that already?
But regardless of that, we need both cross-compiling cases covered on macOS: ARM -> x86 and x86 -> ARM. This is because our current Mac CI is x86.

You mean something like this,
os=Macos
os_build=Macos
arch=armv8
arch_build=x86_64
compiler=clang
compiler.version=14
compiler.libcxx=libc++
build_type=Release
[options]
[build_requires]
[env]

That's the old way of doing it (Conan < v1.24). See here for the new way (2 profile files): https://docs.conan.io/en/latest/systems_cross_building/cross_building.html#conan-v1-24-and-newer

The old way didn't work (probably cause we don't use the variables in the recipe) but I don't see a way to leverage the new way into our existing pipeline

OK, then forget all that. Could you just ensure that macOS ARM on x86 works the same that you already set up x86 on ARM? Add an entry to the changelog and bump the patch version.
