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) and found it was in an excellent condition.

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

For recipe:

• This recipe is using a compiler, which now requires adding a build dependence on {{ stdlib("c") }} as well. For further details, please see META: {{ stdlib("c") }} migration conda-forge.github.io#2102.
