You need to add the asset to the folder structure of the mod. It's not too hard but time consuming. It's referred to as creating a Standalone mod. Usually it's important to get permission from the creator to do so, but often they are glad you ask and usually always say yes. Apachii is very nice about it and I use her work in my mods a lot.

Skyla has an excellent tutorial on this process. Her tut is one of the best I've found.
