Most likely, it means that his file is not found.
Very basically, the C or C++ build is composed of two types of steps: compilation of source code into object files performed by a
compiler, and putting all object files together (with symbol resolution, address translation and other sophisticated tasks) in a single executable code (most usually, *.EXE, *.DLL) performed by a
linker.
Some object files or libraries can be external, already provided to you in a previously compiled form. In your case, one of such files is missing. You need to obtain and compile some version of STL library, not necessarily STLport. You can use one bundled with all versions of Visual Studio and C++ compiler. For that purpose, you should just check a corresponding option in the project properties.

Last three links shown above provide the access to three different implementations of STL. Also, on the Microsoft's page, you will get some overview and the information of the use of the library. This is a standard C++ template library.
