In line with https://dev.opencascade.org/doc/overview/html/occt__upgrade.html#upgrade_occt760_poly the Poly_Triangulation does not provide direct access to the internal arrays anymore - use the accessor functions instead. To keep changes minimal, switch only builds with a new (7.6+) OpenCascade to the new API and keep everything else the same. Related: !1013
