+Subject: [PATCH] cmake: raise cmake_minimum_required to 3.10
+
+Upstream pins cmake_minimum_required to 2.8.6. CMake 4 dropped
+compatibility with policies < 3.5 and warns that < 3.10 will be dropped
+next, so cmake.eclass injects -DCMAKE_POLICY_VERSION_MINIMUM=3.5 and
+emits a QA notice nudging maintainers to update the project. Bump to
+3.10 so the build is clean under modern CMake without the eclass
+workaround.
+
+Bug: https://bugs.gentoo.org/975564
+Upstream-Status: Not submitted (low-activity upstream)
