# ----------------------------------------------------------------------
#
# Top level make procedure.
#
# By default, the make procedure compiles, links and installs
# all executable and library files.
#
# The make procedures proceeds in four steps, namely:
#  1/ make primary internal libraries, including lang, KM3NeTDAQROOT and triggerROOT;
#  2/ make external libraries, including aa and AntaresDAQROOT;
#  3/ make secondary internal libraries, including jaanet;
#  4/ make remainder.
#
# Steps 1/, 2/ and 3/ are handled with a separate target "libs".
#
# The target "examples" can be used to compile all examples.
#
# The target "DAQ" is available for installing only DAQ software. 
#
# The default make procedure compiles all applications for KM3NeT.
# A project specific installation can be made by:
#
#    make Antares
#    make KM3NeT
