@vanzod This is annoying... The patch isn't found because framework isn't considering the right places. It's usually found right next not the easyconfig file, but not when --from-pr is used since the easyconfig file is downloaded to a temporary location (unless the patch is included in the PR). Ugh.

[boegel]

OK, after deep diving into this problem, the issue here is actually that there's no approved review yet for the PR, which makes the mergeable_state set to 'blocked' (rather than 'clean').

When a PR is not marked as 'clean', EasyBuild assumes something is wrong with it, and then it resorts to only downloading the files that are touched by the PR.

For clean PRs, it will download current develop and apply the patch corresponding to the PR on top. In that case, the required patch file will be found, even if it's not touched by the PR...

There may be a way to avoid this, but I need to think about it, so I've opened an issue on this in framework, see easybuilders/easybuild-framework#2630
