Please see the repo readme for directions on how to make PRs on this repo.

Checklist:

• [x] if you have added a CDT, it appears in the cdt_slugs.yaml file and you have rerun the script python gen_cdt_recipes.py.
• [ ] if you have changed the CDT generator code (rpm.py), you have bumped the build number in conda_build_config.yaml and have remade all of the recipes via running python gen_cdt_recipes.py --force
• [ ] if you have added a custom CDT recipe, you have added the name of the CDT with custom: true in the cdt_slugs.yaml file.
• [ ] all CDT recipes have build number set by {{ cdt_build_number }} for old-style/legacy CDTs or {{ cdt_build_number|int + 1000 }} for new-style CDTs
• [x] if you see a warning about a CDT not having a license, you have added the license_file key in the cdt_slugs.yaml file with the path to the appropriate license in licenses/

NOTE: If you make any changes to cd_slugs.yaml, you need to reun the generator code via python gen_cdt_recipes.py. Add the --fast option to make this go more quickly.

This PR replaces #45 and incorporates a fix so that old CDT recipes with url-only changes are not edited.

@basnijholt can you please take a look here and see if the recipes look like they are what you need?

[basnijholt]

Yes, this is everything!

[beckermr]

Great! I am going to fix the license file stuff here. Can you comment on the extra build script bits? That doesn't appear to do anything...

[basnijholt]

It might be correct, I just copied those lines from another package. I wasn’t even sure myself what I was doing. 😅

[beckermr]

I see. We should try and find someone who knows this stuff to comment.

@conda-forge/core?

[beckermr]

I see a dep on mesa-libegl that looks odd given the other excluded dep.

[beckermr]

I didn't see any paths that looked like they need a symlink between mesa-libelg and libglvnd-gles, so I am going to go ahead and merge this. If we need to mark builds as broken later and try again, we can do that.

[basnijholt]

Amazing! Thanks a lot for the help 👍
