PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🧪 No relevant tests

⚡ Recommended focus areas for review Possible Issue Ensure that the inclusion of nvtx3/nvToolsExt.h does not break existing functionality and that nvtx3 is compatible with the current build environment. #include <nvtx3/nvToolsExt.h> Configuration Verify that the new BUILD_WITH_SYSTEM_NVTX flag is correctly handled and that it does not introduce any unintended side effects. BUILD_WITH_SYSTEM_NVTX = True Dependency Management Confirm that the removal of LIBNVTOOLSEXT and the addition of USE_SYSTEM_NVTX do not lead to missing dependencies or unresolved symbols during the build process. ${LIBCUPTI}

This line also needs to be upgraded. cc @nWEIdia

As the above review suggested: please focus on potential compilation breakages, e.g. how should the CMakeFile find nvtx3?
