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 :

cmake -DBUILD_opencv_cvv=OFF

(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

Adding cv:: was all it took. Thank you very much. Next is to see if I can get this built with Cuda 10.0!
