Compiling 4.0.0.0rc Fails
When building overlayfilterwidget.cpp I get the following error:

Seems like a strange error. To fail on such a basic define. Anyone have an ideas?
Thanks, Doug
do you absolutely NEED the cvv module ?
just to "isolate a problem", please try to disable it, like :
(on the other hand: namespace problem ? maybe all it needs is a
cv::COLOR_BGR2HSV?)(try that, too, please ;)
(opencv's buildbots/tests don't have qt by default, so this is never checked !)
Guess I am not so smart, what is the CVV module? I am just following a script posted by [Learn OpenCV] (https://www.learnopencv.com/install-o...)
I will try both your suggestions. And report back. Thanks! Doug
try the 2nd one first ;)
and the cvv module is a way of (debug) visualizing images used in your program, using qt.
actuall, a great thing, IF it works ... it's just not sooo properly tested, and there might be internal errors lurking here
