Download opencv 3.3.0 from 

http://opencv.org/releases.html

Build opencv using cmake

Unzip opencv-3.3.0 and rename the generated file as opencv

cd ~/opencv
mkdir build
cd build

Configue

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

　Build

make -j7 # runs 7 jobs in parallel

Install

sudo make install

##Note:

If you want to uninstall opencv-3.3.0, you can simply enter ~/opencv/build and run the command below

sudo make uninstall

We can have a try

mkdir ~/cmk_learning
gedit main.cpp

Paste the codes below into main.cpp

#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <unistd.h>
using namespace cv;

int main(int argc, char** argv )
{
    if ( argc != 2 )
    {
        printf("usage: DisplayImage.out <Image_Path>
");
        return -1;
    }

    Mat image;
    image = imread( argv[1], 1 );

    if ( !image.data )
    {
        printf("No image data 
");
        return -1;
    }
    namedWindow("Display Image", WINDOW_AUTOSIZE );
    imshow("Display Image", image);

    waitKey(0);

    return 0;
}

Create CMakeLists.txt and edit it:

cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
find_package( OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable( DisplayImage main.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )

Build this project:

cd ~/cmk_learning
cmake .
make

After running the commands above, we have an executable file DisplayImage in ~/cmk_learning

Result

./DisplayImage emt.jpg
