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) 問題。

make時遇到Unsupported gpu architecture 'compute_20' opencv錯誤：
參考這篇文章 ：https://blog.csdn.net/renhanchi/article/details/80493232 解決
重新cmake：
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..
沒有註銷 Anaconda時提示：
libtiff.so.5 recipe for target 'bin/opencv_annotation' failed ld returned 1 exit status
參看：https://www.machunjie.com/deeplearning/264.html 解決後又遇到下面問題：
/anaconda2/lib/libcurl.so.4: no version information available 等錯誤。
後來讀到這篇解釋https://blog.csdn.net/billbliss/article/details/73498307 並locate libcurl.so.4 感覺是與Anaconda庫衝突，於是將Anaconda註釋掉。解決以上問題
