[Insight-developers] Problems compiling today

[Bill Lorensen]

It has to do with symbol visibility. If I do nm on the ITKCommon lib, the
undefined symbols have "t" and not "T". "t" means the symbols are local. If
I remove the -fvisiibility=hidden flag from ITKCommon's CMakeLists.txt
file, the tests build fine.
