No, it's not the same thing. BR2_CMAKE_HOST_DEPENDENCY is to avoid
building CMake if a suitable CMake version is already provided on the
host.

What I'm suggesting as a first step is to avoid building both
host-python3 and host-python. Once this first step is done, and only
host-python3 gets built, then maybe we can think of avoiding the
host-python3 build by using the system-provided version, with something
similar to BR2_CMAKE_HOST_DEPENDENCY.

Meh, OK :-/
