[Insight-users] [ITK Community] ITK External Modules

[Luke Bloy]

I figured it would be more complicated then I thought :)

Here is my situation and perhaps someone can suggest a good path forward.

I'm in the process of of reorganizing the code from my graduate thesis on
diffusion imaging for use in my new lab and for my collaborators. This code
is a mix of filters and executables etc. Ideally Id like to develop an ITK
external module for the core filters and libraries and then another package
for the executable code.

I like the idea of an external module to share with the community etc, but
I need be able to build the executables as a stand alone project on
production systems where I may or may not have access to the ITK build
process.

I think the ideal situation would be to develop an external itk module (get
it registered as a remote module), then in the executables project I would
1) include ITK
2) check if ITK was build with my external module  (is this possible at the
moment???)
3) if not I would build it myself as an external project ( I assume this is
how ITK handles remote modules)

Does this even seem feasible? I am totally open to other ideas

Thanks
Luke
