### Describe the incorrect/future/missing documentation

As a user of CCCL with NVRTC, I would like a simple, standalone example of using CCCL with NVRTC.

While not all of CCCL works with NVRTC, all of the `cuda::` entities and all `cub::Block*` and `cub::Warp*` utilities do.

For simplicity, we can just use the same example kernel from our other example: https://github.com/NVIDIA/cccl/blob/b7697c6f3ee95408b189fe167accc95c45d3a2cc/examples/basic/example.cu#L37-L58

I would like a complete example that compiles this kernel with NVRTC and then executes it and prints the result.
