Question

我正在尝试编写C ++应用程序并出现链接器错误，我想我需要进入项目设置（Visual Studio）并添加一个lib文件，但我不知道此文件的名称和位置是什么，如何找出？

#include "framework.h"
#include "aviDrawDX.h"
#include "aviDrawDX.h"
#include "shellscalingapi.h"
#include "windows.h"
#include <winuser.h>

#define MAX_LOADSTRING 100

// Global Variables:
HINSTANCE hInst;                                // current instance
WCHAR szTitle[MAX_LOADSTRING];                  // The title bar text
WCHAR szWindowClass[MAX_LOADSTRING];            // the main window class name

// Forward declarations of functions included in this code module:
ATOM                MyRegisterClass(HINSTANCE hInstance);
BOOL                InitInstance(HINSTANCE, int);
LRESULT CALLBACK    WndProc(HWND, UINT, WPARAM, LPARAM);
INT_PTR CALLBACK    About(HWND, UINT, WPARAM, LPARAM);

int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
                     _In_opt_ HINSTANCE hPrevInstance,
                     _In_ LPWSTR    lpCmdLine,
                     _In_ int       nCmdShow)
{
    SetProcessDpiAwareness(PROCESS_SYSTEM_DPI_AWARE);
