How to link .lib file in Visual C ++ 2010? Without a link to the project?

I just have a problem that I have been trying to fix for the longest time.

I have a static library project in visual C ++, and I want another project to be able to reference it. So far, I have simply added a link to a static library project that automatically links the library.

I want to be able to reference the library using only the header files and the .lib file. However, I get the error "Unauthorized external character".

I thought I was doing it right - I specified the include directory, the library directory and went into the linker input properties and provided lib as an additional dependency.

I can link to other static libraries this way (e.g. SDL), so why do I get errors when I try to reference mine?

Thanks for the help.

Is the problem not a link to the actual lib file or something inside the library itself? These are the error messages I receive:
