Do you wish to remove temporary build files in /tmp/build\_opencv ?  
(Doing so may make running tests on the build later impossible)  
Y/N

Hi,

CUDA 10.2 cannot compile code for GPU architecture 87.  
Please remove it from the configure.

> <https://github.com/mdegans/nano_build_opencv/blob/master/build_opencv.sh#L110>

For Nano, `-D CUDA_ARCH_BIN=5.3` is enough.  
Thanks.
