So some reason, my .cpp file is missing it's header file. But I am not including the header file anywhere else. I just started so I checked all the files I made

enginuity.h

#ifndef _ENGINE_
#define _ENGINE_

class Enginuity
{

public:
    void InitWindow();

};

enginuity.cpp

#include "Enginuity.h"


void Enginuity::InitWindow()
{

}

main.cpp

#include "stdafx.h"
#include "GameProject1.h"

#define MAX_LOADSTRING 100

// Global Variables:
HINSTANCE hInst;                                // current instance
TCHAR szTitle[MAX_LOADSTRING];                  // The title bar text
TCHAR 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 _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)
{

code.....
#endif

dont know what's going on. The error I get is

1>c:\users\numerical25\desktop\intro todirectx\gameproject\gameproject1\gameproject1\enginuity.cpp(1) : warning C4627: '#include "Enginuity.h"': skipped when looking for precompiled header use
