Issue

It seems that now Windows Azure Pipelines images to not ship atl or anyhow require it to be re-installed manually (see actions/runner-images#9873), that needs to be installed manually for recipes that need it, see:

• llvmdev v18.1.6 llvmdev-feedstock#264 (comment), conda-forge/llvmdev-feedstock@221c9f3
• Rebuild for libxcb 1.16 qt-main-feedstock#269
• [qt5] icu 75 rebuild with additional patches and remove use of cdts qt-main-feedstock#288 (comment)

I may look into this eventually, but I need to get more familiar with conda-smithy codebase.

Thanks for opening. I had put this off because I had been hoping the images would be fixed in a reasonable timeline, but it doesn't look like that's happening.

Given that installing these components takes ~10min, I think we need to put this behind a config option, most likely in conda-forge.yml, and it would probably make sense to put this under
