进入安装包的build文件执行：

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*

若提示默写路径没找到，可忽视，第三条命令列举的可能包含opencv路径，存在的路径已经被删除。
