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.

Thanks @isuruf, that's great!

I guess one thing we have to think about is how to square this with the zip (in the current migrator) that pulls in a specific docker-image. On the arrow-feedstock I worked around this with a commit such as conda-forge/arrow-cpp-feedstock@61be739, but I think a more proper solution would be conda-forge/conda-forge-pinning-feedstock#3624

So we don't need the cross-linux packages and are okay just grabbing the native packages?

[kkraus14]

Instead of hardcoding all of these, there's a json file in the repo that contains all of these that we could parse, for example here: https://developer.download.nvidia.com/compute/cuda/repos/rhel8/sbsa/version_11.2.2.json

It looks like we're getting the CUDA 11.2.0 versions of these packages as opposed to the 11.2.2 versions as well.

@isuruf, lemme know if there's anything I can do to help with this PR

I gave it a shot in #210, but I'm not sure if it's correct; I let it run during the test phase and the CI is green, so it doesn't seem too far off.

Worth noting: the manifest posted by Keith only contains one devel package (cuda-nvml-devel), whereas this PR so far has:

                        cuda-cudart-devel-11-2-11.2.72-1\
                        cuda-driver-devel-11-2-11.2.152-1 \
                        cuda-nvml-devel-11-2-11.2.67-1 \
                        cuda-nvrtc-devel-11-2-11.2.152-1 \
                        libcublas-devel-11-2-11.3.1.68-1 \
                        libcufft-devel-11-2-10.4.1.152-1 \
                        libcurand-devel-11-2-10.2.3.152-1 \
                        libcusolver-devel-11-2-11.1.0.152-1 \
                        libcusparse-devel-11-2-11.4.1.1152-1 \
                        libnpp-devel-11-2-11.2.1.68-1 \
                        libnvjpeg-devel-11-2-11.4.0.152-1

If we need to add those devel packages (most likely necessary to have the headers?!), then that needs more massaging, but shouldn't be too hard.
