Yotta build results in CMake Deprecation Warning, cmake-policies OLD behaviours - c++

Question

I am trying to build the code that is already made as examples for the Micro:bit using the recommended yotta build but after following every step I am getting this error:
yotta build
info: generate for target: bbc-microbit-classic-gcc 0.2.3 at /home/dragos/microbit-samples/yotta_targets/bbc-microbit-classic-gcc
CMake Deprecation Warning at CMakeLists.txt:16 (cmake_policy):
The OLD behavior for policy CMP0017 will be removed from a future version
of CMake.
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.

I have to specify that I did not change any code from the initial git: lancaster-university /
microbit-samples and I have done the update on my system several times. Also, I am running it on Ubuntu 20.04.1 LTS
