> I did a bit of digging on the windows front, and I suspect what's going on is the the MSYS2/mingw cmake is being preferred (I'm not familiar enough with that ecosystem to know if we can override it with something on the system, but that also seems fragile itself). > > https://github.com/raulcd/arrow/blob/e5d521134db4bed8507572fece3b56eb4a1b9158/ci/scripts/r_windows_build.sh#L26-L30 has some info about how to test newer dependencies, I wonder if we (conditionally) use those pacman commands to insall a newer cmake than what's in the CRAN repo (https://cloud.r-project.org/bin/windows/Rtools/4.0/ucrt64/ has the version I'm seeing installed listed, so if we override that one in _our_ builds that might be sufficient. Unfortunately, that won't help us. https://github.com/r-windows/rtools-packages/ is archived; CRAN has moved away from the toolchain that Jeroen was maintaining. We should delete that comment. For newer cmake with older rtools, maybe we can get it from https://github.com/Kitware/CMake/releases/download/v3.31.2/cmake-3.31.2-windows-x86_64.zip or something? Or maybe we can install newer rtools for cmake but use the older rtools for compilers etc.? -- This is an automated message from the Apache Git Service.
