Steps to success: - identify the requirements of this library - see if a currently-supported version of Unity meets those requirements. If you are unsure, a useful forum question might be: "This library requires feature X and the Unity documentation isn't clear on feature X support, can you help me?" If you are unable to do either of those things, you might want to stay away from third party software integration, which is in itself a MASSIVE area of study and rife with deep and complex interoperation concerns.
