How to viewpath in a ClearCase environment to achieve build avoidance?

In a nutshell, the ClearCase view extended path needs to be used to reference derived objects in other views. For example, you are working on a task under a developer's view, dev_view, and you want to reference a builder's view, build_view. The root of the VOB is /vobs/myproj. You may set the VPATH in the dev_view as the following:

    export VPATH=/vobs/myproj:/view/build_view/vobs/myproj

The first node should not use the view extended path; otherwise, nmake will turn the viewpath off since the path name does not match the path where the build starts. You may reference as many views as you want.
