[valgur]

The recipe is almost up to date but it can be fully migrated now that the cpython package is available.

Conan v2 pipeline ❌

Note: Conan v2 builds are now mandatory. Please read our discussion about it.

The v2 pipeline failed. Please, review the errors and note this is required for pull requests to be merged. In case this recipe is still not ported to Conan 2.x, please, ping @conan-io/barbarians on the PR and we will help you.

Why is this necessary even if no python option?

[valgur]

Probably an oversight on my part. I'll simply drop the test_v1_package.
