please advise: project auto build, lbrary is build after executable .....

TO make  my  projects  more  manageble , i separated the  project in libraries instead of a monolite.

I'm using the  project  autobuild  function.

As a  change  is detected,  the  executable  is build  before  the build  of the  library.  This is  waste  of time ....

How can I change  that  the  library is rebuild (if required) before  i build the executable.

Thanks  in advance
