Alas, it is not that easy.  If you have 16 possible libraries you need 
to link against, it may be that library 5 provides what you were 
looking for (and need), but library 14 needed something else from 
library 5 (maybe optional symbols, or an extra library dependency) 
that it failed to provide.  This causes a failure when testing library 
14, but the originating problem was in library 5.

This is actually a pretty common problem.

Similar things occur when testing header files.
