title: How to define relative paths in Visual Studio Project?
body: <p>I have a library and a console application that uses a library. The library has a folder with source and header files.</p>
  
  <p>My project is in a child/inner directory but that library directory that I want to include is in a parent/upper directory.</p>
  
  <p>My project directory:</p>
  
  <pre><code>H:\Gmail_04\gsasl-1.0\lib\libgsaslMain
  </code></pre>
  
  <p>Includes files are here:</p>
  
  <pre><code>H:\Gmail_04\gsasl-1.0\src
  </code></pre>
  
  <p>How can I use paths relative to the project directory, to include folders that are in a parent/upper directory?</p>
