Summary0010418: get_prerequisites() gives bad results if ldd couldn't find full path to item
Descriptionldd gives "not found" if the full path to a library could not be found.
GetPrerequisites.cmake interprets that as the target depending on "not" and I have to debug the script for which library it really is.
It should probably be fixed to return the name of the library, instead of the full path, so one can get relevant warnings/errors from BundleUtilities.cmake.

Here's an example to demonstrate the problem:

====
# pick any non-system library with non-system dependencies
set(lib1 $ENV{HOME}/vtk/build/bin/libvtkFiltering.so)
set(lib2 ${CMAKE_CURRENT_BINARY_DIR}/libvtkFiltering.so)

configure_file("${lib1}" "${lib2}" COPYONLY)
file(RPATH_REMOVE FILE "${lib2}")

include(GetPrerequisites)

get_prerequisites("${lib2}" deps 0 0 "" "")

message("deps are:")
foreach(dep ${deps})
message(" ${dep}")
endforeach(dep)
====

Output of cmake -P <script> is:
deps are:
  /lib/libc.so.6
  /lib/libdl.so.2
  /lib/libgcc_s.so.1
  /lib/libm.so.6
  /usr/lib/libstdc++.so.6
  not

Instead of "not" I'd rather see "libvtkCommon.so.5.5" and "libvtksys.so.5.5" which comes out in the first column of ldd, even without full paths, just so I can see what the problem really is.
