[wenhuapei]

hi, could you please help me? I've installed opencv 3.0.0 and visual studio 2013 and I'm trying to get them working. I followed your steps exactly however I still get a brunch of errors every time i try to debug and run any programs. I'm trying to run this simply program now

#include <opencv/highgui.h>
int main(int argc, char** argv) {
IplImage* img = cvLoadImage(argv[1]);
cvNamedWindow("Example1", CV_WINDOW_AUTOSIZE);
cvShowImage("Example1", img);
cvWaitKey(0);
cvReleaseImage(&img);
cvDestroyWindow("Example1");
}

I added these libraries, it worked:

This is sloppy.
For example you say it's for VS 2014, but you use VS2013. Yes, I know there is probably not much difference, but this is sloppy. 
Still, the use of $OPENCV_DIR inside the property sheet of the application is one I had not thought of.
