Hello there,
I recently installed Opencv on my machine running ubuntu. Everything installed without problems using :
sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
sudo make
sudo make install
Now I created a new project with QT, included "opencv4/opencv2/calib3d.hpp" , and now inside that file it says that it cant find another include "opencv2/core.hpp" .
I looked inside those directories and it is like it added "opencv2/" in fron of al directories. Of corse the directory opencv2 in all those cases doesnt exist.
This is just one example, but it happens with many of the files.
main.cpp:
#include "widget.h"
#include "opencv4/opencv2/calib3d.hpp" //includes without any problem
#include QApplication> // as a normal include
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();
return a.exec();
}
Error message:
/usr/local/include/opencv4/opencv2/calib3d.hpp:47: Fehler: opencv2/core.hpp: No such file or directory
#include "opencv2/core.hpp"
^~~~~~~~~~~~~~~~~~
opencv4/opencv2/calib3d.hpp:

I installed opencv in another directory called /home/tim/OPCV . Inside the include/opencv4/opencv2 directory there is a file called core.hpp. Inside this file, it is trying to include 9 files under the directory "opencv2/core/<file names="">". This directory does not exist, instead it should be "core/<file names="">" . I dont understand why it adds "opencv2/" in front of the include directories.
