title: VC6 setting additional include path using env vars?
body: <p>I can't believe I am asking this...</p>
  
  <p>It has been a while since I used VC6.  I set up what I thought was the correct way to include additional directories for include files (I removed another developer's hard coded paths) and put in something like:</p>
  
  <p>%MY_DIR%\include</p>
  
  <p>but this does not work.  Am I missing something?  Did VC6 not allow this?  It seems like a pretty basic thing to have and now that I think about it it I can't recall ever having done it before...</p>
  
  <p>(I did stop and re-start VC6 after I set the variables)</p>
  
  <p>Google search and a quick search here did not reveal anything.  </p>
  
  <p>EDIT</p>
  
  <p>Apparently I can't vote for my own answer - but it is below:</p>
  
  <p>The syntax is:</p>
  
  <p>$(ENV_VAR)</p>
  
  <p>not</p>
  
  <p>%ENV_VAR%</p>

  <p>I'd rather not have to add to an include env variable - that seems to imply that I have to build from a command line now.  I want to be able to add an environment variable in the project settings.  That seems like a very simple thing to do, but perhaps that was expecting too much from the IDE team.</p>
  
  <p>I am not sure what it means that %MY_DIR% is not taken into account properly...  I did start cmd.exe from the tools menu like you suggested and the env path I set is there and as expected.</p>
