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 (recipes/python-pcl) and found it was in an excellent condition.

Hi @conda-forge/help-python-c, this is ready for review.

A few notes:

• The package is not officially maintained anymore (New maintainer(s) sought strawlab/python-pcl#395). Hence there are quite a few patches with basically all of them stemming from the Debian package (except for the last one that adds conda-forge include directories).
• The package is a RC, but as it's not officially maintained anymore, the best we can get our hands on. It has been shipped in Debian (https://packages.debian.org/sid/python3-pcl).
• I have skipped Windows as the Debian patches only take care of the Unix side of things. I don't think it's impossible to fix, but I have little interest in Windows and can open an issue in the feedstock once it exists to keep track of it (@traversaro, do you have a use case/interest? No worries if not.)

Cool, I did not even know about this, and it could indeed be useful. Anyhow, no one on our side is using it, and given that it is not currently mantained I am not interested in using it.
