Why cant we make this library as all other arduino liabraries.

Thanks fot this great library. But i was wondering that why cant we make this library simple to use like all other arduino libraries. just copy the folder in the libraries folder, and include the header file in the project and you are good to go.
But for this library why do we need to build or do all those other tricks ? Is there some specific reason or am i missing something ?
I have an existing arduino based project, can i simply use this library ? I tried doing what i explained above, but it will throw an error that http_post is undefined.
