Go to your project properties, and:
- Under C/C++ -> Additional Include Directories: add your SFML include directory (in your case, it looks like C:\SFML\include)
- Under Linker -> Additional Library Directories: add the SFML lib directory (probably C:\SFML\lib)
- Under Linker -> Input -> Additional Files (or something like that): make a semicolon separated list of the sfml library files your project is using (e.g. "sfml-graphics-d.lib;sfml-audio-d.lib" for the debug graphics and audio libs, etc.)
Now when you include SFML headers, just write #include <SFML/Graphics.hpp> or whatever.
As for example programs, there are some on the SFML site you can copy and try to run. See the earlier link at the bottom of the page.
