I get as far as:

```
In file included from /opt/SB/debug/SurfaceToolbox/DynamicModeler/Logic/FastMarching/gw_core/../gw_maths/GW_Maths.h:13:
/opt/SB/debug/SurfaceToolbox/DynamicModeler/Logic/FastMarching/gw_core/../gw_maths/GW_MathsConfig.h:139:3: error: "Unknown architecture !"
    #error "Unknown architecture !"

```

Now, I _am_ building on MacOS 11.6, with my CMAKE\_OSX\_DEPLOYMENT\_TARGET set to 10.15, but I have done this before (though a while ago) and had no issues. Perhaps I should build with an up to date deployment target version.

This particular issue is being address in [Fix macOS build error, simplify setting of position independent flag and fix warnings by jcfr · Pull Request #48 · Slicer/SlicerSurfaceToolbox · GitHub](https://github.com/Slicer/SlicerSurfaceToolbox/pull/48) and should be addressed in the next hour.

Got it, thanks @jcfr!

OK, I can build and run on MacOS. Thanks!
