# - 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_LIBRARIES - 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_ENABLE_FINAL - enable this for KDE-style enable-final all-in-one compilation
# 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 )
#    Equivalent to ADD_EXECUTABLE(), but additionally supports KDE3_ENABLE_FINAL
#
# KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )
#    Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
#    It supports KDE3_ENABLE_FINAL
#    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.
#    It supports KDE3_ENABLE_FINAL
