Rebuild for CUDA 12

[conda-forge-admin]

Manually adding a CUDA 12 migration PR since the bot ran into some issues generating it.

Hi! This is the friendly automated conda-forge-webservice.

I've started rerendering the recipe as instructed in #30.

If I find any needed changes to the recipe, I'll push them to this PR shortly. Thank you for waiting!

Here's a checklist to do before merging.

• Bump the build number if needed.

Fixes #30

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 re-render

Seeing this error on CI

Unsupported gpu architecture 'compute_35'

Think the CUDA arch environment variables need a branch for CUDA 11 / 12 (perhaps similar to libmagma)

magma-feedstock/recipe/build.sh

Lines 6 to 8 in be97f11

	# Duplicate lists because of https://bitbucket.org/icl/magma/pull-requests/32
	export CUDA_ARCH_LIST="sm_35,sm_50,sm_60,sm_70,sm_80"
	export CUDAARCHS="35-virtual;50-virtual;60-virtual;70-virtual;80-virtual"

Thanks Daniel! 🙏

Had some suggestions below. Would be interested to hear your thoughts 🙂

[jakirkham]

Would suggest making CUDA 11 the special case. The advantage being that when we drop it, we can just delete som lines from the recipe. Also it will make adding new CUDA 12.x's easier

[jakirkham]

Maybe we can define common versions here and append or prepend others in the conditionals?
