Cannot build C++ code with netbeans and Cygwin

I was trying to build a sample C++ code in Netbeans 8.0.2 with Cygwin 1.7.35 and gcc/g++ version 4.9.2. OpenCV version is 2.4.11, installed under c:/openCV.

Regular C++ code without openCV works okay in Netbeans.

I followed instruction on http://eyalarubas.com/opencv-installation-on-windows-netbeans-mingw.html, but cannot compile with OpenCV. First I tried to link with core library, then add highgui, then add all the rest libraries, still no luck.

What did I miss? Thank you in advance.

Source code:

#include "opencv2/opencv.hpp"
using namespace cv;

int main(int argc, char** argv) {

    VideoCapture cap(0); // open the default camera
    if(!cap.isOpened())  // check if we succeeded
        return -1;
...
}
