[Insight-developers] PROPOSAL: Flattening headers directorystructure at Install time

[J.S.Wijnhout at lumc.nl]

Hi,

Just of thought. You could also change the ITK code to use subdirectories in the #include directives:
#include "Common/..." etc. This way, users will only have to add the main ITK folder to their includes and the old-style of including (without specifying the subfolder) will still continue to work if you decide to include all the ITK subfolders into your include path.

best,
Jeroen

My main concern is the installed base of customers. We can't afford to
break their applications when they upgrade to a new release.

Let's think hard about a way that will improve things for the future
but maintain backward compatibility. This organizational issue is not
the fault of the customers. If there is any pain, it is pain the
development team should bear.
