i had the same problem until i built opencv3 from source w/ cuda: https://github.com/hoangthien94/ORB_SLAM2_CUDA#build-opencv-with-cuda-for-tegra

#6 should help. You need to make sure that nvToolsExt.so is getting linked properly to your usr/lib folder

@Warsin My solution is to install OpenCV by myself. The OpenCV w/Cuda built with JetPack doesn't support this -lnvToolExt. It will take hours to install OpenCV again but worth it.
