The rest API is missing a Link in the header; even though it had one up until about a day ago. This has broken the setup-cmake action, which used to use the “next” in the Link to access pages. Try something like:
curl -I "https://api.github.com/repos/Kitware/CMake/releases"
There is no Link in the header.
See chore: bump checkout version by henryiii · Pull Request #22 · jwlawson/actions-setup-cmake · GitHub for the broken TypeScript-based action, which in turn has broken the CI for pybind11 and other packages.
