cocos2dx 2.2.6 libcurl链接不到

Cocos2d-x
#1

#include “d:\project\cocos2dx\cocos2d-x-2.2.6\cocos2dx\platform\third_party\win32\curl\curl.h”

unsigned char* CCFileUtils::getFileData(const char* pszFileName, const char* pszMode, unsigned long * pSize)
{
unsigned char * pBuffer = NULL;
CCAssert(pszFileName != NULL && pSize != NULL && pszMode != NULL, “Invalid parameters.”);
*pSize = 0;

//CURL *curl = curl_easy_init();
CURL *curl = curl_easy_init();//找不到引用呀

}

工程已经引用了这个
$(ProjectDir)…\cocos2dx\platform\third_party\win32\curl

但是还是报链接不到

CCFileUtils.obj : error LNK2019: 无法解析的外部符号 __imp__curl_easy_init，该符号在函数 “public: virtual unsigned char * __thiscall cocos2d::CCFileUtils::getFileData(char const *,char const *,unsigned long *)” (?getFileData@CCFileUtils@cocos2d@@UAEPAEPBD0PAK@Z) 中被引用

testapp里的CurlTest.cpp却没有问题，但是我直接F5，调试不了curl_easy_init，curl_easy_init直接跑到DLL
// the test code is
// http://curl.haxx.se/mail/lib-2009-12/0071.html
void CurlTest::ccTouchesEnded(CCSet *pTouches, CCEvent *pEvent)
{
CURL *curl;
CURLcode res;
char buffer;

curl = curl_easy_init();
if (curl) 
{
    curl_easy_setopt(curl, CURLOPT_URL, "http://localhost/Resources2/fileLookup.plist");
    res = curl_easy_perform(curl);
    /* always cleanup */
    curl_easy_cleanup(curl);
    if (res == 0)
    {
        m_pLabel->setString("0 response");
    }
    else
    {
        sprintf(buffer,"code: %i",res);
        m_pLabel->setString(buffer);
    }
} 
else 
{
    m_pLabel->setString("no curl");
}

}

何解，在CCFileUtils::getFileData里却引用不了curl_easy_init

#2

调试testcpp里的curl_easy_init();，跑进里去了D:\project\cocos2dx\cocos2d-x-2.2.6\Debug.win32\libcurl.dll

#3

我是直接在testcpp里面做修改的
