cmake opencv3.2 遇到：
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: CUDA_nppi_LIBRARY (ADVANCED) 问题。

make时遇到Unsupported gpu architecture 'compute_20' opencv错误：
参考这篇文章 ：https://blog.csdn.net/renhanchi/article/details/80493232 解决
重新cmake：
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..
没有注销 Anaconda时提示：
libtiff.so.5 recipe for target 'bin/opencv_annotation' failed ld returned 1 exit status
参看：https://www.machunjie.com/deeplearning/264.html 解决后又遇到下面问题：
/anaconda2/lib/libcurl.so.4: no version information available 等错误。
后来读到这篇解释https://blog.csdn.net/billbliss/article/details/73498307 并locate libcurl.so.4 感觉是与Anaconda库冲突，于是将Anaconda注释掉。解决以上问题
