I bumped the python version from 3.4 to 3.5 for the recent py upgrade. OSD was also not being found by default, so I updated the OSD module to point to the default path set through install_deps.sh.
EDIT1: Removed edits to cmake modules and changed pathing in install_deps.sh to install OSD in /opt/lib/opensubdiv instead of /opt/lib/osd
