编译环境 ubuntu1604+opencv3.2+cuda8.0

编译opencv时碰到如下是错误

cmake命令参数如下

cmake -D CMAKE\_BUILD\_TYPE=RELEASE -D CMAKE\_INSTALL\_PREFIX=/usr/local -D INSTALL\_C\_EXAMPLES=ON -D INSTALL\_PYTHON\_EXAMPLES=ON -D WITH\_TBB=ON -D WITH\_V4L=ON -D WITH\_QT=ON -D WITH\_OPENGL=ON -D OPENCV\_EXTRA\_MODULES\_PATH=../../opencv\_contrib/modules -D BUILD\_EXAMPLES=ON -D CMAKE\_LIBRARY\_PATH=/usr/local/cuda-8.0/lib64/stubs -D CUDA\_CUDA\_LIBRARY=/usr/local/cuda-8.0/lib64/stubs/libcuda.so ..

原因是找不到cuda库，解决方式如下(红色为新添加)
