[Insight-developers] ITKModular: Missing makefiles

[Bill Lorensen]

No problem, if that is part of the design.

The only dangerous one is thi:
cd ITK-bin/Modules/Filtering/
DistanceMap; make

Someone may have made changes in another module and think that these is no
dependency in this module. I'll bet I'm not the only one burned here.

We'll just need to be careful.

Thanks,

Bill
