How to set up OpenCV 2.4.9 in Clion on Ubuntu 14.04?

Question

linux

Installed OpenCV by downloading opencv.sh from github. The installation was successful.
My CMakeLists.txt

project(ar_dip)
set(CMAKE_CXX_STANDARD 11)
set(OpenCV_FOUND 1)
FIND_PACKAGE( OpenCV REQUIRED core highgui imgproc)
find_package(PkgConfig REQUIRED)
pkg_search_module(OpenCV REQUIRED core highgui imgproc)
set(SOURCE_FILES main.cpp)
add_executable(ar_dip ${SOURCE_FILES})

The reload was successful.
My code, which I want to take video from the camera and display in the window.

#include <cv.h>
#include <highgui.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char* argv[])
{
    // получаем любую подключённую камеру
    CvCapture* capture = cvCreateCameraCapture(CV_CAP_ANY); //cvCaptureFromCAM( 0 );
    assert( capture );

    //cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH, 640);//1280);
    //cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT, 480);//960);

    // узнаем ширину и высоту кадра
    double width = cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH);
    double height = cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT);
    printf("[i] %.0f x %.0f\n", width, height );

    IplImage* frame=0;

    cvNamedWindow("capture", CV_WINDOW_AUTOSIZE);

    printf("[i] press Enter for capture image and Esc for quit!\n\n");

    int counter=0;
    char filename[512];

    while(true){
        // получаем кадр
        frame = cvQueryFrame( capture );

        // показываем
        cvShowImage("capture", frame);

        char c = cvWaitKey(33);
        if (c == 27) { // нажата ESC
            break;
        }
        else if(c == 13) { // Enter
            // сохраняем кадр в файл
            sprintf(filename, "Image%d.jpg", counter);
            printf("[i] capture... %s\n", filename);
            cvSaveImage(filename, frame);
            counter++;
        }
    }
    // освобождаем ресурсы
    cvReleaseCapture( &capture );
    cvDestroyWindow("capture");
    return 0;
}

What is written below in the console

I can not understand. Why does not it work? The installation of opencv was successful, so it's not about it. All that's left is make?

Try adding to the cmake file:
By the way, it is better to install libraries from packages.
