[-][C++] Several Bundeled Dependencies fail with 4.0[/-][+][C++] Several Bundled Dependencies fail with 4.0[/+]on Apr 1, 2025 This is a particular problem on the Mac because brew updated cmake to 4.0 and there isn't a way to install an older version (through brew). I'm running into this now trying to build jars with my fork of arrow-java.
You can workaround it locally by setting this envvar https://cmake.org/cmake/help/latest/variable/CMAKE_POLICY_VERSION_MINIMUM.html
Describe the bug, including details regarding any error messages, version, and platform.
CMake 4.0 removes support for
cmake_minimum_required(VERSION 3.5)or less and several of our bundled dependencies still use this. When they are built with 4.0 the build fails.Confirmed deps listed as sub-issues.
rapidjson and gflags have not fixed this issue and don't seem to want to release anything. Should we really depend on something like this?
