在C++中调用Lua脚本时要求Lua模块

我在使用VS2015的C++应用程序中运行Lua5.1的非常简单的Lua脚本，没有问题，原始Lua很好。但是当我尝试导入lua模块“socket.http”时，我的应用程序不喜欢它，因为我想象它找不到模块。

我的问题是如何允许我的Lua脚本（从c++运行）访问像socket.http这样的Lua模块？

我的project.cpp

#include "stdafx.h"
#include <iostream>

extern "C"
{
#include <../dependancies/lua51/include/lua.h>
#include <../dependancies/lua51/include/lauxlib.h>
#include <../dependancies/lua51/include/lualib.h>
}

void report_errors(lua_State *L, int status)
{
    if (status != 0)
    {
        printf("-- %s\n", lua_tostring(L, -1));
        lua_pop(L, 1); // remove error message
    }
}

int main()
{
    // create a Lua state
    lua_State* L = luaL_newstate();

    // load standard libs
    luaL_openlibs(L);

    int lscript = luaL_dofile(L, "test1.lua");

    report_errors(L, lscript);

    system("PAUSE");
    return 0;
}

test1.lua

local http = require("socket.http")

errors
