ITK/Release 4/Modularization/Prototype/Tutorial

Overview

• Toy Example design: this tutorial demonstrates the prototype of modularized ITK with an toy example containing six modules and a testing application. The toy modular ITK package contains six library modules and a test application, which reads and writes images in Nrrd format. They are listed as follows:

 * itk-vnl (a subset of numeric libraries of VXL),
 * kwsys (a supporting library for ),
 * itk-common (core classes, macro definitions, typedefs, and other software constructs central to ITK),
 * itk-io-common (classes that support the reading and writing of data),
 * nrrdio (third-party library),
 * itk-io-nrrd (itk wrapper of nrrdio).

• CMake prototyping

 To enable ITK developers download and configure the whole modularized ITK package, redesigning the cmake configurations of the modularized ITK is necessary. The major challenge is to manage dependencies between the modules.  A classic CMake approach is to use "add_subdirectory" to include each module in correct order according to their dependencies. Here we refer this approach as "sub directory" approach (method A). Another approach is to use the state-of-the-art cmake function "add_export_project" to automate the process of pulling codes and data from their repositories. We refer to this second approach as "export project" approach(Method B).

Requirements

• A computer with a network connection
• A build environment (gcc / VS)
• CMake 2.8.2 installed([1])
• Git 1.7.x.x installed ([2])

Method A: SubDir Approach

To enable downloading and configure the whole modularized ITK package for usual ITK developers, the classic CMake approach is to use "add_subdirectory" to include each module in correct order according to their dependencies.
