[ITK-users] Error when Building SimpleITK with SuperBuild

Thu Aug 18 06:14:43 EDT 2016

A related problem, which I've never found a solution for, is that some
cluster software (probably the curl library) is built without ssl support
at a critical point. You may have the same issue. Maybe the configuration
info for curl will tell you one way or another whether this is the case and
you can request a reinstall.
