        -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON

        -D WITH_QT=ON -D CMAKE_INSTALL_PREFIX=/usr/local

        -D WITH_OPENGL=ON -D WITH_V4L=ON

        -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_TBB=ON ..

Answer 1

您需要安装缺少的依赖关系，可以通过以下方法完成：

sudo apt-get install libqt5opengl5 libqt5opengl5-dev

Answer 2

Are you sure you added your Qt folder to your path? Anyway, doing some change like these should help:

1. Go to path ' /home/sharkawey/op/opencv-master/modules/highgui/src/ '.
2. Open file ' window_QT.h ' with your editor.
3. Change the following line:

#include <QtOpenGL>

into:

#include <fullpath/QtOpenGL>

Replace the 'fullpath' string with your actual path of QtOpenGL. You can find it using find command. For instance, if your QtOpenGL is located under ' /home/usr/Qt/ ', you should write as:

#include </home/usr/Qt/QtOpenGL>

Then your compiler knows where to find it. I believe for your case, you may encounter same situations for other files too, and you can solve them similarly.
