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.
