and because the message was not sent to the list I'm a bit puzzled:
The log
https://buildd.debian.org/status/fetch.php?pkg=plastimatch&arch=armhf&ver=1.6.1%2Bdfsg-1&stamp=1431585994&file=log
seems to show that ITK is actually found with cmake 3.2:

CMake Warning at CMakeLists.txt:627 (find_package):
By not providing "FindITK.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "ITK",
but
CMake did not find one.
Could not find a package configuration file provided by "ITK" with any
of
the following names:
ITKConfig.cmake
itk-config.cmake
Add the installation prefix of "ITK" to CMAKE_PREFIX_PATH or set
"ITK_DIR"
to a directory containing one of the above files. If "ITK" provides a
separate development package or SDK, be sure it has been installed.

Do you actually mean cmake 3.0 and cmake 3.1? Indeed, at least up until
2.8.12 cmake had a FindITK module.

It would probably be better to set ITK_DIR (if ITK is indeed not found).
CMAKE_PREFIX_PATH works like the PATH variable, and may contain other
paths.

Well, yes in the sense that ITK < 4.? doesn't work with newer versions
of cmake. The problem is that upstream usually only supports the latest
version. Which brings us back to the problem that ITK3.20 should at some
point be dropped, which in turn would mean that some dependencies would
have to drop support for architectures where ITK4 is not available.

I think it is "/usr/lib/cmake". At least ITK-4.7 installs its files
there in the the ITK-4.7 subdirectory.
Best,
