title: What is the difference between "Include Directories" and "Additional Include Directories"
body: <p>In configuration properties of my project, under the "VC++ directories" there is an entry for "Include Directories". But under "C/C++" option, there is another entry called "Additional Include Directories". Same thing happens with library directories.</p>
  
  <p>What are the difference between these two entries?</p>
