编译安装opencv

cd opencv

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

make 

make install (需要管理员权限)

下面操作可选 ，以上只是安装好了，但是还没有配置环境

sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

编译的时候可以采用下面的命令

`pkg-config opencv --libs --cflags opencv`
