[v3.x] Update to CMake 3.31.10

[sculpordwarf]

Hi,

I followed your classic procedure https://cmake-python-distributions.readthedocs.io/en/latest/update_cmake_version.html to get the latest 3.x version of cmake.
Maybe someone with write access can set the tag, if it gets merged: https://cmake-python-distributions.readthedocs.io/en/latest/make_a_release.html

We made a lot of breaking updates to the build platform in 4.1, I don't think we'd want to ship those back into a patch release. If we wanted to do this, it would probably need to be based on 3.31 (or 4.0, which I think didn't change anything), not 4.1. Is there a reason you need 3.x? 4.x works better for some things like targeting iOS.

Hi henryiii,

Is there a reason you need 3.x? 4.x works better for some things like targeting iOS.
I want to use QNX8 with version 3.x. QNX8 has a deprecation warning spamming the logs:
https://www.qnx.com/developers/docs/8.0/com.qnx.doc.qnxsdp.migration/topic/IDE.html
reported here to cmake:
https://discourse.cmake.org/t/qnx-sdp-8-compiler-flag-lang-c-now-marked-as-deprecated/12695
and the fix to it in 3.31.9:
Kitware/CMake@1660616

I want to use the 3.x version of cmake, because 4.x has breaking changes e.g.:
Compatibility with CMake < 3.5 has been removed from CMake.
Which leads to other problems, I don´t want to fix right now.

Thank you for updating the PR.

You should be able to define -DCMAKE_POLICY_VERSION_MINIMUM=3.5 (either on the command line, or in your CMakeLists.txt before including anything with bad cmake_minimum_required settings that don't have a maximum value), and 4.x should work.

Should be available now.
