I'm getting an error when running the example code in the tutorial:
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.5.4) /build/opencv/src/opencv-4.5.4/modules/highgui/src/window_QT.cpp:208: error: (-27:Null pointer) NULL guiReceiver (please create a window) in function 'cvGetPropWindow_QT'
Aborted (core dumped)
This seems to only happen when calling CvPlot::show(); it works with cv::imshow() and cv::waitKey(). I'm compiling header-only, and using OpenCV 4.5.4.
