ubuntu下完全卸载opencv3.1.0

在ubuntu下删除opencv需要以下步骤：

1.进入opencv的源代码文件夹下的release（这是你在安装opencv时候自己命名的，cmake时候所在的目录）

2.执行以下命令

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*
