[FEA] conan support please

[simshi]

Is your feature request related to a problem? Please describe.
I'm using RAFT by rapids.cmake, while errors occur sometime related to cmake, it's hard to debug, usually I need to remove all build folder to restart again, a waste of time.

Describe the solution you'd like
don't do complicated dependency management in cmake, hope RAFT can support conan (https://docs.conan.io/2/) or other similar tools.

Describe alternatives you've considered

Have you tried Conda?

For example here is how RAFT could be installed with Conda. Feel free to tweak that selector to match what you are looking for
