error LNK2001 w vc++

Jak dolonczyc pliki naglowkowe
#include <D3DX8.h>
#include "D3DApp.h"
#include "D3DFile.h"
#include "D3DFont.h"
#include "D3DUtil.h"
do projektu w visual c++.
W Project->Settings->Link dolancza sie bibloteki, a nie pliki naglowkowe.Podczas kompilacji wyskakuja mi nastepujace bledy jak je usunac.
