How to get the com.nomagic.magicdraw.sysml.jar package if it doesn't exist inside the cameo library already.

I am attempting to make a plugin to create diagrams inside the model; I am able to make UML diagrams, but when attempting to make SysML diagrams, I found out inside the Cameo Lib folder, the com.nomagic.magicdraw.sysml.jar doesn't exist to use the SysMLConstants . How would I go about to get that specific package jar?
