link_libraries `nvToolsExt` is not works

[Vulcan-YJX]

when I use cuvslam with hawk , can't find nvToolsExt.h or cannot find -lnvToolsExt.

• hardware : jetson orin agx
• system : Jetpack 5.1.1
• camera : LI-AR0234CS-STEREO-GMSL2

If found link_libraries in CMakeLists.txt is not works. change if(USE_NVTX) add_definitions(-DUSE_NVTX) link_directories("${CUDA_TOOLKIT_ROOT_DIR}/lib64") link_libraries("nvToolsExt") endif()

to

if(USE_NVTX) add_definitions(-DUSE_NVTX) link_directories("${CUDA_TOOLKIT_ROOT_DIR}/lib64") include_directories("/usr/local/cuda-11.4/targets/aarch64-linux/include") include_directories("/usr/local/cuda-11.4/targets/aarch64-linux/include/nvtx3") link_directories("/usr/local/cuda-11.4/targets/aarch64-linux/lib/") endif()

Solved this problem. But this code style is ugly. I also try to add include_dir to $PATH , It's not works. Why did this problem arise?

Thanks.

The latest version of Isaac ROS is DP3 but within the Isaac ROS Dev container, we're not able to reproduce. The Isaac ROS Dev container adds /usr/local/cuda-11.4/targets/aarch64-linux/lib to your LD_LIBRARY_PATH which allow you to avoid the extra link_directories you needed to add. For the extra include_directories, it is not clear yet why you need them. It could be that with the LD_LIBRARY_PATHs set as in the container (see here), cmake can extrapolate any "include" directories from matched lib directories.
