I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

It seems that sometimes the SP_DIR has the wrong values, I saw something similar also in conda-forge/staged-recipes#27723 .

Now osx-arm64 cross-compilation is failing due to:

This is expected, as the generator should use an executable from the build environment, not the host. We solved something similar in conda-forge/bipedal-locomotion-framework-feedstock#32 .
