unzip opencv-3.4.0.zip
cd opencv

sudo apt install cmake
sudo apt install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg.dev libtiff4.dev libswscale-dev libjasper-dev  

mkdir my_build
cd my_build

## cmake 中会下载安装一个大文件，网速会很慢
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

sudo make
sudo make install

sudo gedit /etc/ld.so.conf.d/opencv.conf

# add this

source /etc/bash.bashrc  
sudo updatedb  

# test

cd opencv***/smaples/cpp/example_cmake
cmake .
