Hello guys,
I am unable to use examples of opencv, I have downloaded at this link:
https://github.com/atduskgreg/opencv-processing
Once unpacked, in the library of processing folder, it was: opencv-processing-master

When I try to run gives the error:

Already tenter change the folder name to opencv only, but to no avail ...
What can I be doing wrong? The other libraries, such as Minin, ControlP5, etc., work normal, but not opencv ...
Abradeço already any help.
thank you
