need help debug with no error, but error on release

edit

Hi all, i am need to openCV and i need some guidance.

I am on the path of learning through online youtubing, when i build the file in debugging, there is no error, but when i tried to build it in release, there is error.

The Error:

1>C:\opencv243\include\opencv\cv.h(63): fatal error C1083: Cannot open include file: 'opencv2/core/core_c.h': No such file or directory
1>
1>Build FAILED.

Program:

#include <C:\opencv243\include\opencv\cv.h>
#include <C:\opencv243\include\opencv\highgui.h>

using namespace cv;

int main()
{
    //create Matrix to store image
    Mat image;
    // initialize capture
    VideoCapture cap;
    cap.open(0);
    // create window to show image namedWindow(“window”, CV_WINDOW_AUTOSIZE);
    namedWindow("window",1);
    while(1)
    {    
        // copy webcam stream to image
        cap>>image;
        // print image to screen imshow(“window”, image);
        imshow("window",image);
        // delay 33ms waitKey(33);
        waitKey(33);    
    }
    return 0; 
}

Thank you very much if you can help me. I need to finish this for my final year project and till this period, i am still in a mist. i have tried Ubuntu but i have no luck in it, so i jump visual studio as i am more familiar in this platform.
