LNK2019使用libcurl

Question

我现在已经收到这个错误了一段时间，所以作为最后的手段，我跟着This video到了这封信......但仍然有同样的错误。所以，这是我制作的代码：

#include <iostream>
#include <string>

#define CURL_STATIC
#include "curl/curl.h"

#ifdef _DEBUG
#   pragma comment (lib, "curl/libcurl_a_debug.lib")
#else
#   pragma comment (lib, "curl/libcurl_debug.lib")
#endif

static int writer(char *data, size_t size, size_t nmemb,
    std::string *writerData)
{
    if (writerData == NULL)
        return 0;

    writerData->append(data, size*nmemb);

    return size * nmemb;
}


int wmain(int argc, wchar_t *argv[], wchar_t *envp[])
{
    std::cout << "Hello curl!";

    std::string content;

    curl_global_init(CURL_GLOBAL_ALL);

    CURL *curl = nullptr;

    curl = curl_easy_init();

    if (curl)
    {
        curl_easy_setopt(curl, CURLOPT_URL, "https://www.youtube.com/watch?v=wjNyT5PhNvI&t=417s");
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &content);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, writer);
        CURLcode code = curl_easy_perform(curl);

        curl_easy_cleanup(curl);

    }

    curl_global_cleanup();

    std::cout << content;

    std::cin.get();
}

错误：

有谁知道造成这种情况的原因是什么？ Linker susbsytem设置为console，字符集设置为unicode，MFC设置为在静态库中使用。
