[ITK-dev] Problems with WikiExamples Remote Module after recent checkin

[Bill Lorensen]

I needed to change the way I configured if building as a remote
module. I needed to explicitly include ITKConfig.cmake before
including the ITKUse.cmake. This simulates a find_package (ITK).

I have checked in the changes to the wikiExamples repo. I'll be
updated the remote module for ITK soon.
