I have some projects using ITK via superbuild that are working now under ITK
3.20 that would no longer compile with this change.

In general I would prefer not to have a hard limit, but if the limit is
necessary, is 50 characters the largest possible limit?  Is the largest path
length in ITK  200 characters?  I am able to build with a longer than 50
character path now using ITK 3.20.

Thanks
