Should we have a flag or something to enable this conditionally and then be able to do these test PRs without adding the get_dependency.cmake files every time>?

I discussed with @robertmaynard about this, since I was missing some historical context here. It sounds like this was tried before in #4643 which was closed without much discussion. I think I would argue that cuML should explicitly depend on thrust and rmm. As I understand it, the only reason not to do so (and to instead get those dependencies via raft) was because of patches that raft needed on thrust/rmm. However, it doesn't look like raft has patches for thrust/rmm at present (see raft's patches directory).

In other words, the historical reasons for the current state (no explicit dependencies) may be outdated and we may want to add explicit dependencies on thrust/rmm so that rapids-cmake is able to properly control these versions.

Other context from @robertmaynard:
The original PR that added thrust and rmm to cuml: #3844
PR that yanked thrust/rmm/etc in 22.02: #4256
