Missing OpenCV header files

I downloaded OpenCV 3.0.0 and compiled with WITH_QT

and it compiled, but when I look into the folder build/install/include/opencv2

, there is only one file named opencv.hpp

and inside:

#include "opencv2/core.hpp"
#include "opencv2/imgproc.hpp"
#include "opencv2/photo.hpp"
#include "opencv2/video.hpp"
#include "opencv2/features2d.hpp"
#include "opencv2/objdetect.hpp"
#include "opencv2/calib3d.hpp"
#include "opencv2/imgcodecs.hpp"
#include "opencv2/videoio.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/ml.hpp"

The problem is that these files do not exist in this directory.

I am on 64-bit Windows and I used Visual Studio 2013 to compile OpenCV because Qt uses Visual Studio as the default compiler on 64-bit Windows and it's weird that the examples compile and everything works, but when I try to create a project on Qt and paste this directory as path, I got an error that opencv2/core.hpp

does not exist. I tried to enable direct from opencv/modules/core/include

, the error persists.

What's happening? What is the proposition of the existence of one file that includes others locally if there are no other files?

after building opencv via cmake, you have to build the INSTALL project (this is not done automatically).



this will copy whatever is needed to build / install / include
