ENH: add real-world-tested and used KDE3 support, and obsolete FindKDE.cmake, which wasn't used by anybody that I heard of

+# - 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_DIR()
+# 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 install 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.
+#    It supports KDE3_ENABLE_FINAL.
+#    A library named kdeinit_<name> will be created and a small executable which links to it.
+#    Supports KDE3_ENABLE_FINAL
+#
