long delay opencv gpu/cuda/GpuMat

When using opencv GpuMat, there is a long delay in a use of the first line code.


In this page,
http://answers.opencv.org/question/52304/long-delay-on-cvgpugpumatupload-after-upgrade-to-gtx970/
There is solution in article.

In one word.



Add 5.2 option in CUDA_ARCH_BIN table when cmake setting.
In my case, this delay problem cleared, after build by set this option.

Thank you.
