latest release [20200616] in jetson nano --> Could NOT find CUDA

hi,

I am building latest release (20200616) in nvidia jetson nano, but I keep getting cuda can;t find error.

Thanks in advance.

ncnn doesn't depend on cuda but it seems that your opencv4 does

[ghimiredhikura]

thanks.
yeah, sorry it was from opencv. solved. closing. :)

For any other who encounter this. In my case, I have compiled and installed opencv from source, that leads to this issue... We can specify cuda path by:

cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-11.0 ..

But my opencv asks for cuda 10.2, so removing that cmake from system path solves my problem:

sudo rm /usr/local/lib/cmake/opencv4/ -r

I have the same problem, how did you solve it
