title: How to include all header files with one include in c++ project?
body: <p>I have a folder containing header (.h) and c++ (.cpp) files. </p>
  
  <pre><code>Folder/ --- file1.h
          --- file1.cpp 
          --- file2.h
          --- ...
  </code></pre>
  
  <p>I have a main.cpp file located in the same directory as the <code>Folder</code> or project (to become library). </p>
  
  <pre><code>// main.cpp
  #include "./Folder/pointtoallheaders.h"
  </code></pre>
  
  <p>How can I include <strong>one</strong> header file that then includes <strong>all</strong> of the header files associated with the project?</p>
