# - Try to find automoc4
# Once done this will define
#
#  AUTOMOC4_FOUND - automoc4 has been found
#  AUTOMOC4_EXECUTABLE - the automoc4 tool
#  AUTOMOC4_VERSION - the full version of automoc4
#  AUTOMOC4_VERSION_MAJOR, AUTOMOC4_VERSION_MINOR, AUTOMOC4_VERSION_PATCH - AUTOMOC4_VERSION 
#                     broken into its components
#
# It also adds the following macros
#  AUTOMOC4(<target> <SRCS_VAR>)
#    Use this to run automoc4 on all files contained in the list <SRCS_VAR>.
#
#  AUTOMOC4_MOC_HEADERS(<target> header1.h header2.h ...)
#    Use this to add more header files to be processed with automoc4.
#
#  AUTOMOC4_ADD_EXECUTABLE(<target_NAME> src1 src2 ...)
#    This macro does the same as ADD_EXECUTABLE, but additionally
#    adds automoc4 handling for all source files.
#
# AUTOMOC4_ADD_LIBRARY(<target_NAME> src1 src2 ...)
#    This macro does the same as ADD_LIBRARY, but additionally
#    adds automoc4 handling for all source files.

# Internal helper macro, may change or be removed anytime:
# _ADD_AUTOMOC4_TARGET(<target_NAME> <SRCS_VAR>)
#
# Since version 0.9.88:
# The following two macros are only to be used for KDE4 projects
# and do something which makes sure automoc4 works for KDE. Don't
# use them anywhere else.
# _AUTOMOC4_KDE4_PRE_TARGET_HANDLING(<target_NAME> <SRCS_VAR>)
# _AUTOMOC4_KDE4_POST_TARGET_HANDLING(<target_NAME>)
