I have been using an external library called Badumna. Recently, it has been open sourced. My problem is how do you include a 3rd party library to an Unreal plugin. In a normal Application Project in Visual Studio, I can find the settings for including a DLL file and its Header directories. But when opening the project properties of an Unreal C++ Project automatically created by Unreal, I can’t find where to link Badumna’s dll and directories.
Take a look at the Apsalar plugin for analytics. It provides the UE4 glue to talk to their library. That’s the path I recommend for you
Forgot to mention that the Project.Target.cs and ProjectEditor.Target.cs are the files to modify to link your lib in. The Apsalar example will show you what that looks like
