Tracking.hpp library not found
I am coding on a tracking application for which i have used opencv (version 3.4.1) c++ platform in a linux operating system (ubuntu version 14.04). Firstly, I am trying to run a sample code given in the following page https://docs.opencv.org/3.4.1/d2/d0a/... But i found an error as Tracking.hpp no found, No such file or directory. How could i include that library Please suggest me with an idea.
Thanks and regards!
