Linking Libraw to VS project

I was able to compile the Libraw .lib, .dll, and examples programs successfully. I've tested the sample programs and they work. However, now I'm trying to link the library into a Visual Studio 2013 project I'm working on and can't figure out why it's not working.
Under Linker->Input->Additional Dependencies, I've added the path to the lib/libraw.lib file. At the top of my code I've also added a #include <libraw.h> and in C/C++->General->Additional Include Directories I've added the path to the LibRaw-0.16.2/libraw folder.
But when I try to compile it can't find the definitions for the functions I'm trying to use:

Error	1	error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl LibRaw::LibRaw(unsigned int)" (__imp_??0LibRaw@@QEAA@I@Z) referenced in function "int __cdecl runDepthFromFocus(int,char * * const)" (?runDepthFromFocus@@YAHHQEAPEAD@Z)	C:\Users\Matteo\Desktop\GSFF_MV_Build\src\matteo\depthFromFocus.obj	Matteo

Please check, that you've

Please check, that you've build DLL correctly:
- you need to add /DLIBRAW_BUILDLIB to compiler flags when you compile DLL parts
- and do not add this flag if you compile user code that uses libraw.

The trick is within libraw_types.h:

#ifdef WIN32
#ifdef LIBRAW_NODLL
# define DllDef
#else
# ifdef LIBRAW_BUILDLIB
#    define DllDef   __declspec( dllexport )
# else
#    define DllDef   __declspec( dllimport )
# endif
#endif
#else
#  define DllDef
#endif

So, when you compile DLL, all needed functions are marked as dllexport

So I tried compiling by

So I tried compiling by running "nmake /DLIBRAW_BUILDLIB -f Makefile.msvc" but it said "NMAKE: fatal error U1065: invalid option 'W' Stop."
I'm probably putting that flag in the wrong spot, but I tried to hack around it by swapping the dllimport and dllexport in libraw_types.h, so that it uses dllexport if I don't define that flag, which is what I'm trying to do anyway.
Doing that, I start compiling by running "nmake -f Makefile.msvc" but I get a bunch of errors (it won't let me post all of them because it thinks it's spam, but they all generally look like the following):

You do not need to pass

You do not need to pass anything to Makefile.msvc, all flags are set OK within this Makefile

If you build LibRaw within

If you build LibRaw within your project, you need to set this define for compiler.

If you build LibRaw using supplied Makefile.msvc (as starting point), all things are already set-up.
Just tested with VisualStudio 2013 (it complains about /arch:SSE2, because this option is default now, but compiles LibRaw and examples OK)

I was just trying to build

I was just trying to build LibRaw with the supplied makefile and then link the created "libraw.lib" or "libraw_static.lib" to my project. So it should already be compiled, just being read by my project when it calls the functions. Is this not an appropriate way to include the source code? It has to be compiled within my code?

You're able to build samples,

You're able to build samples, right?

Samples are build by very simple command (assuming DLL has build before):
cl $(COPT) /Feoutputfilename.exe sample-source.cpp lib\libraw.dll

You may need to adjust COPT variable (in Makefile.msvc) accoriding to your project build flags (runtime library, exception handling).
