Build the IBO package with debugging turned off. The move/copy the
resulting DCUs into a separate directory. In your application
projects include the IBO DCU directory in the search path but NOT the
source directory. You can also achieve the same thing by setting up
the IBO package project to direct the DCU outputs to the required
directory directly - rather than the move/copy.
