The Geant4 examples are quite large, so the installation of these should be an optional component or target.
Fixed in SVN : Revision #49891. log BUGFIX : Bug #1205 : Examples are only installed if GEANT4_INSTALL_EXAMPLES option is set. An option GEANT4_INSTALL_EXAMPLES is provided with a default of OFF. If this option is set to ON, then the examples will be installed as done previously. I have also added the COMPONENT flag in the example install command with value 'Examples' so that component based binary packages will also be able to make the install of the examples optional.
