Major update from 3.31.8 to 4.1.2.
CMake 4.0 introduces a breaking change: compatibility with versions older than
3.5 has been removed. Projects calling cmake_minimum_required() or
cmake_policy() with versions < 3.5 now error out.
To maintain compatibility with existing ports during the transition, the cmake
module now provides MODCMAKE_POLICY_VERSION_OVERRIDE (idea from sthen@)
support:
- MODCMAKE_POLICY_VERSION_OVERRIDE ?= No
- MODCMAKE_POLICY_VERSION_OVERRIDE_VER ?= 3.5
When MODCMAKE_POLICY_VERSION_OVERRIDE is set to "yes", CMake is instructed to
accept policy versions down to the specified minimum (default 3.5) via
-DCMAKE_POLICY_VERSION_MINIMUM. This allows older ports to build while
acknowledging they may use deprecated features.
