# - Find the KDE3 include and library dirs, KDE preprocessors and define a some macros
#
# This module defines the following variables:
# KDE3_DEFINITIONS - compiler definitions required for compiling KDE software
# KDE3_INCLUDE_DIR - the KDE include directory
# KDE3_INCLUDE_DIRS - the KDE and the Qt include directory, for use with INCLUDE_DIRECTORIES()
# KDE3_LIB_DIR - the directory where the KDE libraries are installed, for use with LINK_DIRECTORIES()
# QT_AND_KDECORE_LIBS - this contains both the Qt and the kdecore library
# KDE3_DCOPIDL_EXECUTABLE - the dcopidl executable
# KDE3_DCOPIDL2CPP_EXECUTABLE - the dcopidl2cpp executable
# KDE3_KCFGC_EXECUTABLE - the kconfig_compiler executable
# KDE3_FOUND - set to TRUE if all of the above has been found
#
# The following user adjustable options are provided:
#
# KDE3_BUILD_TESTS - enable this to build KDE testcases
#
#
# It also adds the following macros (from KDE3Macros.cmake)
# SRCS_VAR is always the variable which contains the list of source files for your application or library.
#
# KDE3_AUTOMOC(file1 ... fileN)
# Call this if you want to have automatic moc file handling.
# This means if you include "foo.moc" in the source file foo.cpp
# a moc file for the header foo.h will be created automatically.
# You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
# to exclude some files in the list from being processed.
#
# KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN )
# If you don't use the KDE3_AUTOMOC() macro, for the files
# listed here moc files will be created (named "foo.moc.cpp")
#
# KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h )
# Use this to generate DCOP skeletions from the listed headers.
#
# KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h )
# Use this to generate DCOP stubs from the listed headers.
#
# KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui )
# Use this to add the Qt designer ui files to your application/library.
#
# KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc )
# Use this to add KDE kconfig compiler files to your application/library.
#
# KDE3_INSTALL_LIBTOOL_FILE(target)
# This will create and install a simple libtool file for the given target.
#
# KDE3_ADD_EXECUTABLE(name file1 ... fileN )
# Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.
#
# KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )
# Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
# If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
# It creates and installs an appropriate libtool la-file.
#
# KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN )
# Create a KDE application in the form of a module loadable via kdeinit.
# A library named kdeinit_<name> will be created and a small executable which links to it.
#
# The option KDE3_ENABLE_FINAL to enable all-in-one compilation is
# no longer supported.
