title: Create Xcode project from .cpp files
body: <p>I have many C++ projects/files I would like to create into a<code>Command Line Tool</code> file type <code>.xcodeproj</code> for debugging purposes. The only way I can think of doing this successfully is to create a new <code>Command Line Tool</code> Xcode project > <code>Type: C++</code> then add the C++ project directory or files. Is there anyway to do this without creating a new project and manually adding the file(s) to it?</p>
  
  <p>Note: Xcode opens the individual .cpp files by default but they're not associated as a <code>Command Line Tool</code> or have an <code>.xcodeproj</code> file type.</p>
