Need updated OpenCascade/CGM for SMTK.
The superbuild version of OCE is old (~500 commits behind the canonical tpaviot/oce repo on github) and causes crashes on Mac OS X 10.10. I have been using 6d4ba0 from tpaviot along with a recent CGM 14.1 branch (containing a fix for compiling CGM w/ OCC 6.8.0) for a while with no issues.
