[Insight-developers] Problem with ITK_SOURCE_DIR var in ITKConfig.cmake.in

[Stephen R. Aylward]

Regardless, this broke backward compatibility.

ITK's backward compatibility policy MUST also apply to its CMake files.

Perhaps there was a really good reason for doing it, and it wasn't 
removed just because it was "bad" - but regardless, this should have 
been posted to the developers and users list, included in a CHANGES.txt 
file, and announced in every viable way to keep these questions from 
arising.
