Including "itk_zlib.h" is the defined way to get the zlib ITK is
configured to use whether it is the built in one or the system one.
In the case of the built-in itkzlib, it ensures that our zlib.h header
is included and not the system one.  This is important because ours
provides the mangling.

You'll have to hack the external code to include the proper name.
Otherwise we cannot be sure it will get the right header.
