make it easier to include rmm in other projects

[rongou]

Right now if we want to include RMM in other cmake projects using CPM, we'd have to do something like this:

CPMAddPackage(
    NAME rmm
    GIT_REPOSITORY https://github.com/rapidsai/rmm
    GIT_TAG 0cc1380523d31b2f044ecc74b457b228f8aea0c8
    OPTIONS "BUILD_TESTS OFF" "BUILD_BENCHMARKS OFF"
)

With this change, it can be done using the short form:

CPMAddPackage("gh:rapidsai/rmm#0cc1380523d31b2f044ecc74b457b228f8aea0c8")

This is also the recommendation from Modern CMake (https://cliutils.gitlab.io/modern-cmake/chapters/testing.html).

Can we retarget this to 21.08? We're at the very end of burndown for 21.06 where I'm not comfortable trying to squeeze this into 21.06.

@kkraus14 looks like CI for 21.08 hasn't been set up yet?
