m_pMainWnd is not set by MFC. It is provided to be used in your code. Common usage is to assign the address of your main frame window (or the main dialog with dialog based applications) upon creation in InitInstance():
CMyApp::InitInstance()
{
...
    // create main frame window; CMainFrame is your CFrameWnd derived class
    CMainFrame * pMainFrame = new CMainFrame;
    // load menus, accelerators, icons
    if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
        return FALSE;
    m_pMainWnd = static_cast<CWnd*>(pMainFrame);
...
}

Purpose is to have access to your main frame class from all modules of your app:
CMainFrame * pMainFrame = static_cast<CMainFrame*>(AfxGetApp()->m_pMainWnd);
