How to bundle static library into NSIS plugin - c++

Question

I'm new in NSIS and C++.
I write a NSIS plugin to check a license with http request with VS2010.
But the plugin only work on the computers with VS2010 installed.
I guess the reason is the libraries like "ws2_32.lib" is not bundled in the package.
I want the installation package with this plugin worked on the computers without C++ installed.
Is there any idea how to solve it?
Thanks a lot.
Here is my code.
// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include <WinSock2.h>
#include <iostream>
#include <stdlib.h>
using namespace std;
#include <string.h>
#include <stdio.h>
#include "./../nsis/pluginapi.h"
#include <windows.h>
#include <Wincrypt.h>
#pragma comment(lib,"crypt32")
#pragma comment(lib,"./../nsis/pluginapi-x86-unicode.lib")
#pragma comment(lib, "ws2_32.lib")

I guess the reason is the libraries like "ws2_32.lib" is not bundled in the package.
No, that thing is only consumed by Visual C++ linker. In runtime, the corresponding DLL is taken from C:\Windows\System32\ws2_32.dll
Most likely reason is C and C++ runtime DLLs. By default, Visual Studio C++ projects use dynamic linking to these libraries. For an installer plugin, a good way to fix is switch to static C++ runtime. Right click on the project, Configuration properties, C/C++, Code Generation, change the “Runtime Library” setting to Multi-threaded Debug (/MTd) for debug configuration and Multi-threaded (/MT) for release configuration.
P.S. I would recommend a higher-level library for HTTP networking, such as WinHTTP or WinINet. Modern Internet has migrated from http to https.
