I downloaded and put the library in the right place but I get this error message :

This is the example code I am trying to compile:
#include <Poco/Net/HTTPClientSession.h>
#include <Poco/Net/HTTPRequest.h>
#include <Poco/Net/HTTPResponse.h>
#include <Poco/StreamCopier.h>
#include <Poco/Path.h>
#include <Poco/URI.h>
#include <Poco/Exception.h>
#include <iostream>
#include <string>
using namespace Poco::Net;
using namespace Poco;
using namespace std;
int main(int argc, char **argv)
{
if (argc != 2)
{
cout << "Usage: " << argv[0] << " <uri>" << endl;
cout << " fetches the resource identified by <uri> and print it" << endl;
return -1;
}
try
{
// prepare session
URI uri(argv[1]);
HTTPClientSession session(uri.getHost(), uri.getPort());
// prepare path
string path(uri.getPathAndQuery());
if (path.empty()) path = "/";
// send request
HTTPRequest req(HTTPRequest::HTTP_GET, path, HTTPMessage::HTTP_1_1);
session.sendRequest(req);
// get response
HTTPResponse res;
cout << res.getStatus() << " " << res.getReason() << endl;
// print response
istream &is = session.receiveResponse(res);
StreamCopier::copyStream(is, cout);
}
catch (Exception &ex)
{
cerr << ex.displayText() << endl;
return -1;
}
return 0;
}
Any help will be appreciated. Thanks
