The ITK4 packaging is perfectly fine under the Debian Med umbrella where
it is now. They do need to handle their transitions better. There are
still a number of packages that depend on libinsighttoolkit4.7 whereas
libinsighttoolkit4.8 is now in unstable.

Also have a look at the outstanding bugs for insighttoolkit4, these show
that it's a beast to build (requiring > 40 GB disk space) (#759794), and
also documents why it's only built on amd64 & i386 (#724711).

How to best help get insighttoolkit4 into shape to not hinder OTB
packaging is best discussed with Steve M. Robbins <smr@debian.org> &
Gert Wollny <gw.fossdev@gmail.com> who appear to be the active
maintainers within the Debian Med team beside being listed as Uploaders.

If ITK4 uses CMake components, OTB could require only those for its build.

It may be sufficient to specify the required ITK components for OTB in
Modules/ThirdParty/ITK/CMakeLists.txt instead of the full find_package()
it currently does:

 set(OTBITK_EXPORT_CODE_BUILD "find_package(ITK REQUIRED HINTS ${ITK_DIR})")

This pulls in all of ITK, not just the components required for OTB. It
should probably do the same as
Modules/ThirdParty/ITK/otb-module-init.cmake.

As Johan said, this is a bad example, don't follow it.
