+Subject: [PATCH] libcomps: Support builds with CMake 4+
+
+- Bump minimum required version to 3.10, the lowest one CMake 4+ don't complain
+  about. It's also possible to use 3.5, but that results in a deprecation
+  warning. The 'cmake_minimum_required()' invocation has been moved before the
+  initial 'project()' call as CMake complained about the wrong order.
+
+- Set policy CMP0148 [0] to OLD to unblock build without additional changes.
+  Eventually, the usage of the 'PythonInterp' and 'PythonLibs' find modules will
+  be need to be updated to use 'Python3' instead.
+
+- Set policy CMP0175 [1] to NEW and fix warnings.
+
+- Fix the 'No TARGET ... has been created in this directory' error in
+  'src/python'.
+
+- Fix 'Utility target <foo> must not be used as the target of a
+  target_link_libraries call' errors (see [2]).
+
+- Mark the 'check' library as required when tests are enabled to prevent test
+  targets from linking a non-existing library in case it's not installed.
