title: c++ how do you open folder as a project in visual studio?
body: <p>I have a folder which is a c++ project but it's not a visual studio project.</p>
  
  <p>How can I open the folder as a project or convert it into a visual studio project, so that I can <code>make</code> it?</p>
  
  <p>There's no <code>vcproj</code> or <code>sln</code> files, which is expected. I'm familiar with Visual Studio and would like to take advantage of that environment.</p>
