[Gate-users] implicit ROOT dependencies (was: Cannot compile GATE v7.0.)

[Patay Gergely]

I guess you tried to compile without ROOT support (GATE_USE_ROOT=OFF).
Well, it just won't work, because the ARF (and a few other) source code will 
still hold some dependencies on ROOT in the source code.

* The simple way is to build with ROOT (GATE_USE_ROOT=ON).

* The other way is to fix the missing #ifdef G4ANALYSIS_USE_ROOT guarding lines 
in the source.

With this patch applied, the code can be compiled with or without ROOT.

Please note that if you choose to build Gate without ROOT, you will not be able 
to use a couple of its features (ARF, TriCoinc, DigiRoot, LinacBeam, various 
Actors, just to name a few).
