Resolve my simple external symbols, pls!

I have created my dynamic library in VS2013 , 32bit.
Now I have two files: MYLIB.lib and MYLIB.dll

I want to use it in class UNewActorComponent_FORREDSPHERE. I use my includes with

#define MYLIB_API __declspec(dllexport)
#define MYLIB_API __declspec(dllimport)

What is the proper place to add my library?
I have already added /EHsc MYLIB.lib to additional commands(but I suppose it is wrong place)

The “Property Pages” of my project is much “smaller” than in usual projects where I can add a library easily.

So I don’ty know how to do it and, therefore, I have this error:

error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl State::State(void)" (__imp_??0State@@QEAA@XZ) referenced in function ........

I just need simple solution. I very appreciate step-by-step solution, because I am not professional of UE4. Thanks!

External Lib/Dll files should be implemented as a plugin;
It sounds like you try to attach them as usual VS project, that won’t work because the engine uses UHT and UBT systems to package the project and it won’t find your external libs if you don’t implement a plugin module for them…
When packaging your game it would simply fail even if you manage to add the DLL while in editor.
