C++ Script vs C++ Plugin

Please advise which method (C++ script or a C++ plugin) would be easier to interface with another C++ library.

Basically, I'd like to pass a couple channels to a shared library (dll file) and have it return a calculated value into a new DEWESoft channel.

The external library would be this package:http://www.coolprop.org/ or something similar.

For example, this method would be used to calculate the density of nitrogen gas at a measured temperature and pressure.

Thanks.

Based on your application we suggest you use the processing plugin.
