Importing a DLL into a static library

So, i have a DLL that i have tested and i am able to use it. (i do not have the source code, only the .lib and the .dll ).

I would like to create a wrapper around the functions and make a static library of it.

Creating a static library works fine, although if i use any of the functions in the DLL it does not work.

The header for the DLL is something like this:

#ifdef __cplusplus

extern "C"

#endif

#ifdef WIN32 //<< this one is true

#define __API __declspec(dllimport)

#else

#define __API extern

#endif

__API void function_I_would_like_to_use();

I am using VS2012.

So in my project settings i have added the .lib under addition dependencies.

However, how can i tell the compiler to also include the DLL?

As of now it compiles fine , but obviusly i still need the DLL since the functions i would like to use are defined as 

dllimport.  

Is it possible to import from the DLL and then export it to the static library?

Thx in advance
