Help me please

Hello I'm a Newbie at programing and need a little help with that.
here is my question. I need to write the program that uses functions from the source.. TUIO C++ API . can u give me som step by step insctructions how to do that. I allready have written the program in which I want to impliment this functions the only problem is that HOW CAN I IMPLEMENT the fyunctions from downloaded source ?

here is what I tried. I downloades the sources. and in header file of my program added include "TuioServer.h" and so on all the headers of that source. also I added additional directory path where I downloaded the source. is that enough to use functions I get this error :
error LNK1120: 22 unresolved externals

Are your compiling the downloaded source files and linking them to your own source?
