如何在C++中为Windows的GDI正确设置库？

#include <Windows.h>

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // 注册窗口类
    WNDCLASS wc = {};
    wc.lpfnWndProc = WindowProc;
    wc.hInstance = hInstance;
    wc.lpszClassName = L"MyWindowClass";
    RegisterClass(&wc);

    // 创建窗口
    HWND hwnd = CreateWindowEx(0, L"MyWindowClass", L"Window Title", WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, 800, 600, nullptr, nullptr, hInstance, nullptr);

    // 显示窗口
    ShowWindow(hwnd, nCmdShow);

    // 消息循环
    MSG msg = {};
    while (GetMessage(&msg, nullptr, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
    case WM_PAINT:
    {
        PAINTSTRUCT ps;
        HDC hdc = BeginPaint(hwnd, &ps);

        // 创建画笔和画刷
        HPEN hPen = CreatePen(PS_SOLID, 2, RGB(255, 0, 0));
        HBRUSH hBrush = CreateSolidBrush(RGB(0, 0, 255));

        // 选择画笔和画刷到设备上下文
        SelectObject(hdc, hPen);
        SelectObject(hdc, hBrush);

        // 绘制矩形
        Rectangle(hdc, 100, 100, 300, 200);

        // 释放画笔和画刷
        DeleteObject(hPen);
        DeleteObject(hBrush);

        EndPaint(hwnd, &ps);
        break;
    }
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hwnd, uMsg, wParam, lParam);
    }

    return 0;
}
