Add Thrust CMake example with flexible device system, update docs #4500

alliepiper · 2025-04-18T16:44:32Z

This fixes #4452.

Adds new thrust_flexible_device_system example that demonstrates how to write a CMake build system for a project that uses Thrust and allows the device-system to change based on configure-time options.
Updated existing docs to clarify intended audience and cross-ref user docs/examples.
Updates minimum CMake version in examples to match CCCL requirements.
Uses the local repo/HEAD when building the CCCL examples from a CCCL build. This speeds things up drastically when github decides to be slow, and makes it possible to test local changes without pushing to github.
Adds the cudastf example to the build system to ensure that it is actually tested.

… backend.

…ce and cross-ref user docs.
