【opencv基础】linux系统卸载opencv

找到opencv某个版本的源码文件，进入build目录；

cd opencv_build
sudo make uninstall 
cd .. 
sudo rm -r build 
sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*

之后再删除源码目录即可；
