I am using the curl-8.8.0 version. I have installed using vcpkg(2024.07.12) . I have built a library as static. When linking libcurl.lib to sample code unable to build the sample code.

Sample code:

#include <iostream>
#include "curlcurl.h"
using namespace std;

size_t WriteCallback(void *contents, size_t count, size_t size, void *data)
{
    try
    {
        ((std::string*)data)->append((char*)contents, count * size);
        return count * size;
    }
    catch (...) {}
    return 0;
}

int main(int argc, char* argv[])
{
    struct curl_slist *headerlist = NULL;
    static const char buf[] = "Expect:";
    headerlist = curl_slist_append(headerlist, buf);
    CURL *curl = curl_easy_init();
    CURLcode res;
    long code;
    std::string response;
    string url = "http://localhost:6000/e/cfg";
    if (curl)
    {
        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);
        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
        curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
        curl_easy_setopt(curl, CURLOPT_POSTREDIR, CURL_REDIR_POST_ALL);
        curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
        curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "GET");
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);
        curl_easy_setopt(curl, CURLOPT_USERAGENT, "libcurl-agent/1.0");
        res = curl_easy_perform(curl);
        curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &code);

        curl_easy_cleanup(curl);
        curl_slist_free_all(headerlist);
        curl_global_cleanup();
    }
    return 0;
}

I have linked following libraries:

ws2_32.lib
Normaliz.lib
Crypt32.lib
Wldap32.lib 
libcurl.lib
libssl.lib

I have try to build the sample code. But it is not building.

Error:

I am using Visual Studio 12 2013 for my sample code. How to resolve the above error?.
