[Insight-developers] itk zlib with third party libraries?

[Jean-Christophe Fillion-Robin]

Folks,

Few months ago, while working on Slicer, I needed to build zlib. For that
purpose, I extracted the tree used in CMake, made sure it could be
installed and found using FindZLIB and finally added the
option ZLIB_MANGLE_PREFIX so that it can be configured with any prefix.

Consider looking at: https://github.com/commontk/zlib/commits/
