# Makefile template for ROOT dictionary generation
#
# This is a common include file which handles generation of the ROOT dictionary
# files. It creates:
# - the dict.cxx              (variable DICTCPP)
# - the dict.h                (variable DICTCPP:.cxx=.h)
# - optional: the linkdef.h   (variable MODULE postfixed by -LinkDef.h)
#
# If the MODULE_DHDR variable is set in the package definition lib<module>.pkg
# to a custom LinkDef file, the automatic generation of the LinkDef header is
# disabled. Instead, the specified one is used.
#
# usage:
#  1. set variable CLASS_HDRS to the class header files
#  2. set DICTCPP variable to dictionary c++ file name
#     e.g. <module>-DICT.cxx (<module> replaced by your module name)
#  3. add the source file name to the list of generated sources
#     nodist_lib<module>_la_SOURCES  =  $(DICTCPP)
#  4. add additional include files which are necessary for the compilation
#     of the dictionary files and which are not part of the CLASS_HDRS to
#     the DICTINCLUDE variable
#  5. include this file from your Makefile(.am)
#     e.g. include ../make.dict
