title: Can you use environmental variables in qt creator?
body: <p>So I use a bunch of libraries in the code I'm currently working in.  Right now I include them by doing things like <code>win32:LIBS += "C:/my/location/Tools/libcurl/trunk/lib/Debug/curllib.lib"</code>.  However, I have an environmental variable that defined <code>%TOOLS%</code> as <code>C:/my/location/Tools/</code>.  I tried to simply change my include to <code>win32:LIBS += "%TOOLS%libcurl/trunk/lib/Debug/curllib.lib"</code>, but it could not find the files.  I looked online and this should be doable.  Am I missing something simple, like a way to tell Qt creator to look at window's environmental variables?</p>
  
  <p>Thanks!</p>
