@asmorkalov could you double check on CUDA_ARCH_BIN after cmake, please ?
This patch won't break the build but it's supposed to limit CUDA_ARCH_BIN to 5.3 only on Nano

Yes, 5.3 is reported in console and I see CUDA_ARCH_BIN:STRING=5.3 in CMakeCache.txt.

It seems this PR just wraps CUDA_HOST_COMPILER in quota. I am OK with it, but it seems unnecessary to introduce a new variable.

For my case with TX2, with following cmake command:

cmake -DWITH_CUDA=On -DBUILD_PERF_TESTS=Off -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ../opencv

I get the following output:

--   NVIDIA CUDA:                   YES (ver 10.0, CUFFT CUBLAS)
--     NVIDIA GPU arch:             53 62 72 70
--     NVIDIA PTX archs:

The compute capability number of TX2 is 62.
