Linking a DLL in an Unreal 4 Plugin

So I am writing a plugin that will be using some .dll .lib packages. I've successfully got the plugin's Build.cs to include the .lib but it wont compile. I get an external symbol not found error that just wont go away. I've placed the .dll at all the locations I can think of where the linker should pick it up to no avail (Binary folders in and out of the plugin, (Win64 and "ThirdParty")), Public and Private Folders in the plugin, project root, you name it.

Does anyone know how to link a .dll for use in a plugin? (fyi, I just want to expose part of the .dll to Blueprints or use them in C++ functions that get exposed to Blueprints).

How do you know that your Build.cs includes the .lib file?

Also, you can not include just every lib file, it has to be compiled with the correct compiler options or the linker will not like it (see here). Adding DLLs is more complicated than adding libs, because you have to do it at runtime: https://wiki.unrealengine.com/Linking_Dlls
