title: How to fix a Static Library?
body: <p>I'm trying to learn how to debug static libraries and I am trying to fix JsonCpp in particular.  </p>
  
  <p>What project settings can I use to see exactly what's being linked in the output window in Visual Studio?</p>
  
  <p>==================================================================================</p>
  
  <p>Here are the errors that I am getting:</p>
