CMake Error: Variables are set to NOTFOUND

Question

I installed cuda first using cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64.deb. Now I\'m trying to install OpenCV 3.3.0 But i\'m getting CMake Err

Answer 1

@api55 solution solves the errors related to CUDA_nppi_LIBRARY. So just follow the steps and it works (for me on Ubuntu 16.04 with opencv 3.3). Make sure your GPU architecture is supported. I've Fermi which is no longer supported. The solution is to install Cuda-8 with gcc-5 compiler when installing opencv 3.3 with cuda support.
