Actually I didn't even try for compatibility.  Those libraries were
never intended for use by outside projects.  From
Insight/Utilities/itkThirdParty.cmake before my recent changes:

# The in-tree third-party libraries are not exported.  We only need
# the include directory inside the tree.  If using a third-party
# library from the system, though, make sure the system include
# directory is consistent inside and outside the tree.

As a result projects that needed the libraries used hacks to get to
them.  I wasn't aware of anyone doing this.  My implementation to export
the libraries for real (a new feature) breaks those hacks.

Fortunately restoring them is easy.

Good idea.
