I recently had problem in compiling icub-main in a conda environment with Python 3.10 installed while the system (Ubuntu 24.04) had Python 3.12 installed. This happened as the old (pre-3.15) behaviour of CMake was to always find the most recent Python version, instead of getting the highest in the path (see https://cmake.org/cmake/help/latest/policy/CMP0094.html).

The problem can be solved without raising the minimum required CMake by setting the CMP0094 policy to NEW, but I think it was good idea to directly raise the policy_max (i.e. the version used for the policies of CMake) argument of cmake_minimum_required to 3.28.
