Add custom labels to the recipe to indicate CUDA version?

[leofang]

Just found that rapidsai has its own CuPy recipe:
https://anaconda.org/rapidsai/cupy/files
They have custom labels to indicate against which version of CUDA the recipe is built. I think this is a nice feature because it's impossible to tell this from the build string. How do we add this?

btw, @jakirkham, any chance you know who is maintaining rapidsai's recipes?

I looked at the conda-forge infrastructure, and to do this we'd need to submit a PR to conda smithy and modify the build script. Don't think it worth the effort...

Ah sorry! I completely missed this.

RAPIDS did use labels, but we moved away from that in favor of the cudatoolkit versioned approach that we have also adopted here. The relevant discussion is in issue ( conda-forge/conda-forge.github.io#687 ).

Cool, thanks for the pointer John!
