Summary:                    add new behavior for find_library
Description: 
Quoting Brad's suggestion:

CMake's design assumes that the dependencies don't move after a project
is built.  If one of VTK's dependencies is rebuilt and puts a library
in a new location, VTK could be rebuilt to know about the new location.
I guess Debian's packages can be rebuilt without rebuilding all their
dependents so long as the ABI is compatible.  This is necessary for a
sane update path for clients because otherwise if one low-level library
is rebuilt for a bugfix then the entire system would have to be updated.

A solution on the CMake side would be to (optionally) change the
behavior of find_library.  Currently it reports the full path to a
library, but when that full path is inside an implicit linker search
path the generated link line ends up with the -l form anyway.  We could
teach find_library to optionally report the library by only its name
if the full path found is in an implicit search path.  If the behavior
were controlled by a global setting then that setting could simply be
added as a -D argument in Debian package build rules.
