Hi Brian,
What is the version passed to cmake_minimum_required for your project?
(Typically the first line in your top-level CMakeLists.txt).
I suspect if you set it to a version higher than 3.1 the warnings will
disappear (I believe it is set to a version older than that, hence the
policy warnings).
Regards
