ITK Modularization Efforts and Tooling Overview
Explore the modularization efforts in ITK led by Bill Hoffman at Kitware, including Qt integration, Boost involvement, ExternalProject_add module in CMake 2.8, and more. A detailed dive into module dependencies, Git sub-modules, and expansion outside the main repository.

We are not alone Qt modularization effort Boost modularization effort Ryppl
ExternalProject_add Module introduced in CMake 2.8 Allows the download, configure, build and install of software via custom commands Kitware Source Article: October 2009 http://www.kitware.com/products/html/BuildingExterna lProjectsWithCMake2.8.html ARL CSE Avoid the Easter Egg Hunt!
Titan Example Google Protocol buffers CLAPCK Curl VTK Qt Trilinos Boost Titan
Trilinos (Multi-Package Dashboard) http://trilinos-dev.sandia.gov/cdash/index.php Main Project Sub Projects
git sub-modules http://chrisjean.com/2009/04/20/git-submodules- adding-using-removing-and-updating/
Having our cake and eating too, ITK two ways itk-complete All of ITK with git sub-modules for each For ITK developers itk-optional An ExternalProject_add version that checks out each sub-module as needed For applications using ITK
Module Dependencies A git sub-module itk-depends CMake Code for handling module depend information The depend information for each module Used by both itk-complete and itk-optional Exploring ways to keep the depend information on branches in each modules git
Proof of Concept git clone git://itk.org/itk/itk-complete.git git clone git://itk.org/itk/itk-optional.git
Allows for Expansion Outside Main Repository Anyone should be able to create an ITK module, and have it work in this system Each module should contain Source Tests Depend information Documentation
Demos cmake-gui turn on off modules Load itk-optional in VS
The Hard Part. We need to partition ITK
