Apparently, passing `-DGEANT4_USE_FREETYPE=ON` to cmake causes two non-free fonts: a) arialbd.ttf and b) helvetica.ttf to be installed into `${CMAKE_INSTALL_DATADIR}/fonts`, which seems to be contrary to what one may expect when enabling freetype font rendering.

From `source/analysis/CMakeLists.txt`:
```
if (GEANT4_USE_FREETYPE)
  install(DIRECTORY fonts/
    DESTINATION ${CMAKE_INSTALL_DATADIR}/fonts
    PATTERN ".svn" EXCLUDE
  )
endif()
```
and

```
> ls test/geant4.10.06.p02/source/analysis/fonts
> arialbd.ttf  helvetica.ttf

```

No licensing specific to these two font files are specified in the sources; therefore, assuming these are from the well-known Arial and Helvetica family respectively, they are not freely redistributable, in contrast with geant4's own license.

This is a stumbling block for us to build and provide openSUSE packages from the default repositories, and we would deeply appreciate if you could resolve or clarify this licensing situation.

Thanks.
