title: Doxygen Documentation using makefile
body: <p>I have written a program in c++ and I would like to generate the executables using a makefile. This works, however I also have some Doxygen style comments in my code, and I want my makefile to automatically generate the HTML page with the documentation. Unfortunately I can't figure out how this should be done correctly. So far the docs part of my makefile looks like:</p>
  
  <pre><code>docs:
      doxygen ./Doxyfile
  </code></pre>
  
  <p>I am guessing I will need to add some extra files, could someone please clarify the procedure for me?</p>
