title: eclipse cdt - how to set the active build configuration from the command line
body: <p>In eclipse CDT from the command line I can create workspaces, import and build projects, etc. This works.</p>
  
  <p>I'm trying to change the 'active configuration' of a project from (X) to (Y) 
  In the GUI, I can do this:  Right click on the project name, go down to "Build Configurations" -> "Set Active" </p>
  
  <p>I want to do this from the command line, I'm no java developer otherwise I would set a breakpoint and step through the java code and figure this out {I don't have a java build environment setup either, simply to complex for my needs right now}</p>
  
  <p>Option 1 - the setting is stored in a file.</p>
  
  <p>Somewhere - in a saved file - Eclipse has to have some setting that marks a project as "the active configuration" but I can't seem to find this.</p>
  
  <p>Option 2 - something from the command line ... that will let me do this</p>
  
  <p>Any suggestions?</p>
