I think there has been some confusion here.  The option to use a system 
library has been removed only for JPEG because ITK now has jpeg8, 
jpeg12, and jpeg16 libraries that are all compiled specially (part of 
recent GDCM changes).  The options for tiff, zlib, and png are still 
supposed to work, and they are provided specifically for people trying 
to create packages on systems like Linux.  I will investigate this 
problem when I get a chance.
