# FindKDE3
# --------
#
# 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.
