Fix nvtx3 build export (#615)

Fixes the following error:

```
CMake Error at /home/coder/rmm/build/conda/cuda-12.2/latest/rmm-targets.cmake:52 (set_target_properties):
  The link interface of target "rmm::rmm" contains:
    nvtx::nvtx3-cpp
  but the target was not found.  Possible reasons include:
    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.
