I’ve submitted a fix for PortPlacement extension’s build error. We’ll see tomorrow if it works.

There are many other modules for simulating port placement and checking tool trajectories. See [this post](https://discourse.slicer.org/t/how-to-do-surgical-simulation-with-slicerigt/16906/5) for more information.
