i have wlroots installed in /usr/lib/wlroots

Ugh! So it looks like this might work if we add all of the cffi dependencies to setup_requires. Unfortunately, this then also means these packages are required for sdist, which should be able to just build the source and doesn’t need to have the dependencies, which would greatly complicate the release creating in github actions (not impossible to do, but would take a bit of work to get fixed up). There is some discussion that build_system is the replacement for setup_requires, but it looks like that gives the same error.

For now, if you re-install pywlroots, but first install cffi, pywayland, and xkbcommon, then it should work. Note that you might need to remove ~/.cache/pip so you re-download and rebuild the packages. We can move this issue over to the pywlroots repo.

Great! I was able to get a fix pushed into pywlroots and a new version cut, so this shouldn’t be a problem moving forward!
