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

Tried the way api555 said, but when cmake, it also build sm20, I did a little more, two ways:

1.in file OpenCVDetectCUDA.cmake, line 133, in the "foreach(ARCH IN LISTS ARCH_LIST)" loop，add "elseif(ARCH MATCHES "20")" between if and else.

2.in file OpenCVDetectCUDA.cmake, line 46, "set(_generations "Fermi" "kepler" "Maxwell" "Pascal")" just delete the "Fermi"

I prefer the second way, may it do a little help.
