how and wat do i do to do that ?
You do the same things as with any other library: add "SFML/include" to the include search paths, add "SFML/lib" to the library search path, and link to the SFML libraries that you need (sfml-xxx.a).
If you don't know how to do that, I suggest that you search some documentation or tutorials about your IDE; these steps are not specific to SFML, you'll have to repeat them for any other library that you're going to use.
By the way, do you want to use
SFML or
CSFML?
