Right now this project requires a minimum CMake version of 3.2. Since the new release of CMake (3.27), versions < 3.5 are considered deprecated and will be removed in the future.
This is why we should increase the CMake minimum version. A possible new minimum version is 3.16 as this is the one that ships with Ubuntu 20.04.
cmake ..
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):

CMake that the project does not need compatibility with older versions.
