Unresolved symbols when linking a program using libcurl

Question

I know this is programming questions but I'm just frustrated trying to figure out what I'm doing wrong..

I'm using visual studio 2010 and followed all the steps here: http://curl.haxx.se/libcurl/c/visual_studio.pdf

When I try to compile my solution I keep getting this error:

1>------ Build started: Project: LibCurl, Configuration: Debug Win32 ------
1>LibCurl.obj : error LNK2019: unresolved external symbol __imp__curl_easy_cleanup referenced in function _main
1>LibCurl.obj : error LNK2019: unresolved external symbol __imp__curl_easy_perform referenced in function _main
1>LibCurl.obj : error LNK2019: unresolved external symbol __imp__curl_easy_setopt referenced in function _main

Source:

// LibCurl.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <stdio.h>
#include <curl/curl.h>

int main(void)
{
  CURL *curl;
  CURLcode res;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
    res = curl_easy_perform(curl);

    /* always cleanup */ 
    curl_easy_cleanup(curl);
  }
  return 0;
}

I've been using static version of libcurl, and to link my program against it properly, I had to add definition:

CURL_STATICLIB

to build configuration of my project.
