 Tap the KeckCAVES formula repository:
+~~brew tap KeckCAVES/keckcaves~~
 
-    brew tap KeckCAVES/keckcaves
+    brew tap gfacciol/homebrew-keckcaves
 
 Then just install the formula you want as per usual!  E.g.
 
-    brew install vrui-examples
+    brew install vrui
+    brew install lidarviewer
