Hi Brad,

That could be possible, the idea would be to have a Slicer_EXTENSION_SOURCE_DIRS advacned options that the developer could set to be a list of extensions source dirs.

Then, when building (and then packaging) Slicer, the modules associated with the extensions would be automatically built (and then bundled) within the Slicer package.

That's why the "if(NOT Slicer_SOURCE_DIR)" statements play their role.

Please, create an issue on Slicer tracker.

Hello,

I wish to install a customized slicer with ITKv4 and SimpleITK on a networked drive with my custom extensions.

I have read the documentation here:
http://wiki.slicer.org/slicerWiki/index.php/Documentation/4.1/Developers/Versioning#How_to_create_a_Slicer_package

So with the latest changes I am able to package Slicer just fine. The problem comes with the extension(s)...

When I launch the installed Slicer I want the extension to be there, for any user. I am not really sure the best way to do this. As I will likely have different versions of Slicer and different versions of my extension, I need to some how configure each versioned Slicer.app to use my extension. Ideally, I'd like my extension to become part of the .app, for easy portablility. It's apple-like to be able to just drag the .app around ( say off to your laptop ) and have it just work.

I have had some success, by running "make package" in my extension. Then manually mounting the dmg, and copying the files to the internal of the Slicer.app. This seems to work, but it's a little manual and error prone.

I am now wondering if there is a place in the Slicer source tree I could clone my Extension into, and have Slicer just pick it up and build my Extension with Slicer, kind of like the ITK's Modules/External directory. This would make things easier, one build, one make package.

Is there a better way to accomplish this? I just want a .app which contains my Extension.

Thanks,
Brad
