+Subject: [PATCH] Update CMake minimum required version to 3.10
+
+CMake 4 removed compatibility with CMake versions < 3.5, and versions
+between 3.5-3.10 are deprecated.
+
+This change updates the minimum required version to 3.10 to ensure
+compatibility with modern CMake versions including CMake 4.x.
+
+This issue is affecting NixOS users (see
+https://github.com/NixOS/nixpkgs/issues/450274) and will likely impact
+other distributions as they upgrade to CMake 4.x.
