ROOT fails to compile with current VecGeom
The source file geom/vecgeom/src/TGeoVGShape.cxx currently includes VecGeom headers from their "old" locations:
https://github.com/root-project/root/blob/5f2ced2567e005b286ba3b726c356324119dcb39/geom/vecgeom/src/TGeoVGShape.cxx#L18-L35
The "new" location is prefixed by VecGeom/ since January 2020 (see commit), so it's not possible to compile ROOT with VecGeom 1.1.6 or later.
I'm tentatively assigning @agheata (because it's geometry) and @Axel-Naumann as we briefly discussed during the team meeting if it makes sense to fix this or deprecate and drop the code if apparently nobody is using it.
I'll fix the compilation and provide a test for this interface.
