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.

Looks like there's a setuptools-ish compat issue on Windows when Python >= 3.12:

File "%SRC_DIR%\forgebuild\giscanner\msvccompiler.py", line 43, in __init__
    CCompiler.__init__(self, verbose, dry_run, force)

TypeError: Compiler.__init__() takes from 1 to 3 positional arguments but 4 were given

update: this is actually about setuptools >= 81, reported upstream.
