CMake 4.0 dropped support for projects with a minimum required version below 3.5. libarchive, as well as possibly other dependencies, had older versions set so they now fail to build. GitHub Actions and MSYS2 were very quick to update their CMake version and there isn't a tagged vcpkg release with a fix for libarchive yet, so we will use a specific commit for now.
