# 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. See kdelibs/cmake/modules/KDE4Macros.cmake.
# _AUTOMOC4_KDE4_PRE_TARGET_HANDLING(<target_NAME> <SRCS_VAR>)
