CMake 4.0 removed compatibility with CMake versions below 3.5. Therefore, it errors out on projects with a cmake_minimum_required() less than 3.5. (Since CMake 3.31, it already warns that compatibility with versions below 3.10 is deprecated.) By passing CMAKE_POLICY_VERSION_MINIMUM=3.5, we indicate that we are ok with configuring this project with the policies of CMake 3.5, even if the project files themselves don't state it. This flag is only recognized by CMake 4.0; older versions will only warn that the manually specified variable is unused.
