is possible but not its default). Conversely, if VTK has been built with
qt5, it will be disabled in OpenCV unless it too is being built with qt5.
+Since opencv version 4.1.1, Qt5 is the required widget framework
+(Qt4 is insufficient). Therefore qt5 is now a required dependency,

This package is configured to generate python bindings for Python 3 (via
dependency on the numpy3 package). If bindings for Python 2 are required,
the numpy package is required when building opencv.
