getting a warning regarding cmake whiile doing catkin_make in ROS noetic

Question

I've build a few workspaces for different project but i never got any error, but this time, got this msg.

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_policy):

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

can anyone explain this, also how can i resolve this warning. (I'm using ros noetic on ubuntu 20.04)

These are the apt packages with catkin in there name:

ii  python3-catkin-pkg                                                1.0.0-100                             all          catkin package library

I've updated the cmake version to 3.16.3 but i'm getting similar msg:

My ros-noetic install does not generate those warnings for the commands that you shared. Please edit your question to list the apt packages you have installed which have catkin in the apt package name. — Mike973, Commented Jan 13 at 19:17
Also tell us which version of cmake you have installed. It should be v3.16.3. If you have upgraded cmake, your environment is not compatible with ros-noetic. — Mike973, Commented Jan 13 at 19:26

You should expect to have weird problems if you use an unsupported version of cmake with ros-noetic. You are expected to use the standard version from the standard ubuntu-20 apt repository.

You need to downgrade your cmake to version 3.16.3. How you do that depends on how you installed the upgrade. If you used apt to upgrade cmake, I expect that you can use apt to downgrade it.

These warnings inform us that the Catkin build system uses some features of CMake that are seen as deprecated and will be removed at some point in the future.

Normally, you should just upgrade your project to avoid using deprecated features of CMake, but I understand it is not so easy when the build is tied to the aging Catkin build system or when you are building projects that are not yours and do not plan to maintain them.

As the deprecated features are still supported by the CMake you use, I suggest you ignore these warnings because they are not errors and not something "unclear." Within your project, they be silenced by putting at the top of CMakeLists.txt:

cmake_minimum_required(VERSION 3.27.7)
cmake_policy(SET CMP0148 OLD)

But I suggest not touching CMakeLists.txt of files the projects you just want to build and not edit or maintain.

You may also downgrade CMake as proposed in another answer, but this restricts access to the new features you likely want to learn and use. I think this is not worthwhile as long you still use the backward-compatible CMake version.
