I understand the process of using a 3rd party library to access functions outside of my code base, but how do i actually set up Visual Studio 2005 to include them in the project.

I have a 3rd party library with some headers, some cpp's, and some .lib files.

In the projects properties I add the top level external library directory as an include directory, I add the additional library directory at the same level put this is project properties too.

In the .cpp file where I use the functions, do I put the #include in its header file? In the top level projects header file? in the cpp?

I've tried all that, but I get "unresolved external symbol"... grrrrrrrrrrrrr
