Are you stil encountering the same issue?
This is my cmake invocation.
https://github.com/lancethepants/tomatoware/blob/master/scripts/buildroot.sh#L808-L843
I typically update cmake to the most recent whenver I get around to updating my
project. The latest I've used is 3.21.4. Looks like you're using the very
newest, so I doubt it's the difference between my version and your version.
