+Subject: [PATCH] Specify CMake policy range to avoid deprecation warning
+
+CMake 3.27 started issuing a deprecation warning for any
+cmake_minimum_required() call that specified a minimum
+version older than 3.5. Specifying a version range instead of
+a simple minimum version avoids that warning without
+raising the minimum supported CMake version. The NEW
+policy behavior will be used for all policies introduced up to
+CMake 3.14 with this change.
