This model allows to load arbitrary GDML files [@gdml] as passive materials. All volumes from the GDML file which are contained within the world volume are processed and added to the geometry of the simulation.

This functionality requires Geant4 to be built with GDML support enabled. This can be enabled via CMake when compiling Geant4 using



```

cmake -DDGEANT4_USE_GDML=ON ..

```
