  • Revert parts of PR ENH: Make quadninja optional and add macOS, aarch64 Linux builds #7.
• Add guards to ensure looptools.hh is not distributed in include/ninja and include/quadninja.

Hi! This is the friendly automated conda-forge-linting service.

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.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.
