Do I have to rebuild OpenCV so that it supports CUDA?

I have read some tutorials saying that before opencv4 CUDA was not active so that you had to rebuild OpenCV4 from source.
I also did

$ python

>>> import cv2

>>> print cv2.getBuildInformation()

and I could indeed see that I could not use CUDA.
However the latest news is that now with the latest JetPack, it comes with OpenCV4…1.1

My question is, do I still have to rebuild OpenCV4 from source to use CUDA?
