Geospatial Creator errors with Cesium 1.21.0+

[CisDutchRose]

What's happening

After importing ARCore Extensions and Cesium (1.24.0), my project won't compile. Turns out Google.XR.ARCoreExtensions.GeospatialCreator.Editor.asmdef is referencing an assembly called CesiumRuntime, but Cesium for Unity ships its assembly as CesiumForUnity from v1.21.0+. So the reference is broken and you get a bunch of compile errors.

How to reproduce

1. Install Cesium for Unity.
2. Import ARCore Extensions with Geospatial Creator.
3. Wait for Unity to recompile.
4. Errors show up.

The fix that worked for me

1. Go to Packages > ARCore Extensions > Editor.
2. Open Google.XR.ARCoreExtensions.GeospatialCreator.Editor.asmdef.
3. Under References, swap CesiumRuntime for CesiumForUnity.
4. Let it recompile
5. Errors are gone.
