I've added opencv lib to path put I still get this error

I have pushed a change swapping the Maven dependency and updating the OpenCV version. You shouldn't have to mess with the path yourself as the dependency used contains the binaries needed to use the library.

Thanks much for your reply. I've downloaded the update and opened it using Netbeans10. But I get error during building

I've been able to rectify the above error, then another situation
