cmake 3.31 is broken: CMake Error: Could not find CMAKE_ROOT !!!

[njzjz]

See this error in the CI, which can be reproduced:

CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/share/cmake-3.31
CMake Error: Error executing cmake::LoadCache(). Aborting.

I’d be fine to yank this while we figure it out, but it doesn’t seem like I have permission to yank, @jcfr?

[Transurgeon]

can confirm we are getting this error too (from installing wheels for cvxpy->osqp->qdldl->cmake).

I don’t have permission to yank, so I’ll have to try to fix this tonight. I’m assuming it’ll show up on any system that does not have a system CMake (I.e, like ci or my machine)

[jcfr]

Yanking now.

3.31.0 yanked ✅️

Ah, wow, this only shows up if there's a CMakeLists.txt present. I hadn't realized that at first; my docker reproducer wasn't reproducing but adding the CMakeLists.txt does trigger it.

Got the bug. CMake's inspecting the first arg to find the root path. But in #555 I didn't give it the full path.

We have links pointing back here, both on PyPI:

https://github.com/scikit-build/cmake-python-distributions/blob/0c316e2d1a68b84ce5220fad05fe706848e670b0/pyproject.toml#L36

And in the readme:

https://github.com/scikit-build/cmake-python-distributions/blob/0c316e2d1a68b84ce5220fad05fe706848e670b0/README.rst?plain=1#L88-L90

Not sure where else we could add more links?

New 3.31.0.1 release will be up a few hours.

Thanks @henryiii for sorting this out 🙏💯
