Checklist

• Title of this PR is meaningful: e.g. "Adding my_nifty_package", not "updated recipe".
• Recipe uses the v1 recipe.yaml format, or this PR explains the exceptional requirement for deprecated v0.
• License file is packaged (see the v1 example recipe for an example).
• Source is from official source.
• Package does not vendor other packages. (If a package uses the source of another package, they should be separate packages or the licenses of all packages need to be packaged).
• If static libraries are linked in, the license of the static library is packaged.
• Package does not ship static libraries. If static libraries are needed, follow CFEP-18.
• Build number is 0.
• A tarball (url) rather than a repo (e.g. git_url) is used in your recipe (see here for more details).
• GitHub users listed in the maintainer section have posted a comment confirming they are willing to be listed there.
• When in trouble, please check our knowledge base documentation before pinging a team.
