  7. Update external/LCGCMT/LCGCMT_58/LCG_Settings/cmt/requirements
    Update LCG_home to the top level location of the Gaudi build to something like:

  10. Set up to use CMT v1r20p20090520, for example:
    setenv CMTBASE /afs/slac/g/glast/users/heather/gaudi_v21r4/CMT
    setenv CMTVERSION v1r20p20090520
    source $CMTBASE/$CMTVERSION/mgr/setup.csh
    setenv CMTCONFIG win32_vc71
    setenv CMTPATH /nfs/slac/g/glast/users/glground/heather/buildingGaudi_v21r7/GAUDI/GAUDI_v21r7:/nfs/slac/g/glast/users/glground/heather/buildingGaudi_v21r7/external:/nfs/slac/g/glast/users/glground/heather/buildingGaudi_v21r7/external/LCGCMT/LCGCMT_58:/afs/slac/g/glast/users/heather/gaudi_v21r7
  11. Gaudi uses CMT, so building goes something like this
    We choose to limit the Gaudi packages we build to (in this order):  GaudiKernel, GaudiSvc, GaudiUtil, GaudiAlg, GaudiAud
    For each package, enter the cmt directory and do:
      cmt broadcast "cmt config"
      source setup.sh
      make
