title: How to add additional libraries to Visual Studio project?
body: <p>Allergro is an open souce C++ addon library for graphics manipulation. How do I add this library to my compiler?</p>
  
  <p>The instructions don't work for me as I have Windows 7. I don't know if the OS matters. I have the Visual Studio Express Edition. The library is a .dll file. How do I add it to my projects?</p>
