Compilation Warnings

[vvolkl]

The compilation output is not very useful at the moment due to many spurious warnings. I had a look, and a large volume is due to shadow warnings between Gaudi and Geant4. They only appear when the CMake configuration includes the line

include(${Geant4_USE_FILE})

which can be safely removed for many, but not all FCCSW subdirectories. Another trigger seems to be

gaudi_depends_on_subdirs(GaudiKernel)

It is not clear if the last statement is still needed. There seems to be a major rewrite of the Gaudi CMake Configuration going on, I will ask there.
