[Smtk-developers] Reading a IGES/STEP file using SMTK

Actually, that module only requires CGM (which was once part of Cubit but was open-sourced**). If you build CGM with OpenCascade, then you will be able to load STEP and IGES files via OpenCascade.

We have a "superbuild" (a CMake project to fetch and build a package PLUS all of its dependencies) of SMTK that will build OpenCascade and CGM here: https://gitlab.kitware.com/cmb/cmb-superbuild . Even if you don't use the superbuild, you can see how it configures OpenCascade and CGM.
