Your includes look okay, but you're missing the libraries to link to 
(i.e. the list of libraries with the -l option).  It looks like you 
haven't created a project from existing sources (with a Makefile) so 
you'll have to configure your project's libraries from the "Linker" 
section of your project's properties.  HTH.
