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.

@conda-forge-admin, please rerender

[ymontmarin]

@jcarpent after that, the branch v1 can be deleted

[ymontmarin]

@jcarpent the branch I mentioned is in hpp-fcl repo: https://github.com/conda-forge/hpp-fcl-feedstock/tree/v1

[ymontmarin]

@jcarpent nevermind, as a maintainer I can do it myself on hpp-fcl

[ymontmarin]

This is the only changes that matter, the other change is just the deletion of the file to build with v1
