title: Edit $(IncludePath) "macro" in Visual Studio 2010
body: <h2>Visual Studio 2010 ("Project Properties" dialog)</h2>
  
  <p>I've installed Visual Studio 2010 Ultimate and it has apparently imported the default directories for my Win32 C++ includes and libraries.  Every new Win32 C++ project I create automatically adds my old include/library directories which screws up my build.</p>
  
  <p><strong>So my question is this:</strong>  How can I edit <code>$(IncludePath)</code> in Visual Studio 2010? </p>
  
  <p><em>or is $(IncludePath) specific to this project and only the result of the "Inherit from parent or project defaults" checkbox? (in which case the question turns into:  How do I edit project defaults for that since it appears to be depreciated in Visual Studio options)</em></p>
  
  <p>Thanks!</p>
  
  <p>NOTE:  The %include% environment variable is not defined in Windows.  It does show up if you enter "echo %include%" in the VS2010 command prompt (not the Windows command prompt), but it's not the same values as what I'm trying to get rid of in the screenshots)</p>
