#
# The variable INSTALL_TARGETS_DEFAULT_ARGS can be used when installing libraries
# or executables into the default locations.
# The INSTALL_TARGETS_DEFAULT_ARGS variable should be used when libraries are installed.
# It should also be used when installing applications, since then
# on OS X application bundles will be installed to BUNDLE_INSTALL_DIR.
# The variable MUST NOT be used for installing plugins.
# It also MUST NOT be used for executables which are intended to go into sbin/ or libexec/.
#
# Usage is like this:
#    install(TARGETS kdecore kdeui ${INSTALL_TARGETS_DEFAULT_ARGS} )
#
# This will install libraries correctly under UNIX, OSX and Windows (i.e. dll's go
# into bin/.
#
#
# The following variable is provided, but seem to be unused:
#  LIBS_HTML_INSTALL_DIR    /share/doc/HTML            CACHE STRING "Is this still used ?")
#
# The following user adjustable options are provided:
#
#  KDE4_ENABLE_FINAL - enable KDE-style enable-final all-in-one-compilation

#  KDE4_ENABLE_FPIE  - enable it to use gcc Position Independent Executables feature
#  KDE4_USE_COMMON_CMAKE_PACKAGE_CONFIG_DIR - only present for CMake >= 2.6.3, defaults to TRUE
#                      If enabled, the package should install its <package>Config.cmake file to
#                      lib/cmake/<package>/ instead to lib/<package>/cmake
#  KDE4_SERIALIZE_TOOL - wrapper to serialize potentially resource-intensive commands during
#                      parallel builds (set to 'icecc' when using icecream)
#
# It also adds the following macros and functions (from KDE4Macros.cmake)
#  KDE4_ADD_UI_FILES (SRCS_VAR file1.ui ... fileN.ui)
#    Use this to add Qt designer ui files to your application/library.
#
#  KDE4_ADD_UI3_FILES (SRCS_VAR file1.ui ... fileN.ui)
#    Use this to add Qt designer ui files from Qt version 3 to your application/library.
#
#  KDE4_ADD_KCFG_FILES (SRCS_VAR [GENERATE_MOC] [USE_RELATIVE_PATH] file1.kcfgc ... fileN.kcfgc)
#    Use this to add KDE config compiler files to your application/library.
#    Use optional GENERATE_MOC to generate moc if you use signals in your kcfg files.
#    Use optional USE_RELATIVE_PATH to generate the classes in the build following the given
#    relative path to the file.
#
#  KDE4_ADD_WIDGET_FILES (SRCS_VAR file1.widgets ... fileN.widgets)
#    Use this to add widget description files for the makekdewidgets code generator
#    for Qt Designer plugins.
#
#  KDE4_CREATE_FINAL_FILES (filename_CXX filename_C file1 ... fileN)
#    This macro is intended mainly for internal uses.
#    It is used for enable-final. It will generate two source files,
#    one for the C files and one for the C++ files.
#    These files will have the names given in filename_CXX and filename_C.
#
#  KDE4_ADD_PLUGIN ( name [WITH_PREFIX] file1 ... fileN )
#    Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
#    It supports KDE4_ENABLE_FINAL.
#    If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
#
#  KDE4_ADD_KDEINIT_EXECUTABLE (name [NOGUI] [RUN_UNINSTALLED] 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 KDE4_ENABLE_FINAL
#    If the executable doesn't have a GUI, use the option NOGUI. By default on OS X
#    application bundles are created, with the NOGUI option no bundles but simple executables
#    are created. Under Windows this flag is also necessary to separate between applications
#    with GUI and without. On other UNIX systems this flag has no effect.
#    RUN_UNINSTALLED is deprecated and is ignored, for details see the documentation for
#    KDE4_ADD_EXECUTABLE().
#
#  KDE4_ADD_EXECUTABLE (name [NOGUI] [TEST] [RUN_UNINSTALLED] file1 ... fileN)
#    Equivalent to ADD_EXECUTABLE(), but additionally adds some more features:
#    -support for KDE4_ENABLE_FINAL
#    -support for automoc
#    -automatic RPATH handling
#    If the executable doesn't have a GUI, use the option NOGUI. By default on OS X
#    application bundles are created, with the NOGUI option no bundles but simple executables
#    are created. Under Windows this flag is also necessary to separate between applications
#    with GUI and without. On other UNIX systems this flag has no effect.
#    The option TEST is for internal use only.
#    The option RUN_UNINSTALLED is ignored. It was necessary with KDE 4.0 and 4.1
#    if the executable had to be run from the build tree. Since KDE 4.2 all
#    executables can be always run uninstalled (the RPATH of executables which are not
#    yet installed points since then into the buildtree and is changed
#    to the proper location when installing, so RUN_UNINSTALLED is not necessary anymore).
#
#  KDE4_ADD_LIBRARY (name [STATIC | SHARED | MODULE ] file1 ... fileN)
#    Equivalent to ADD_LIBRARY(). Additionally it supports KDE4_ENABLE_FINAL,
#    includes automoc-handling and sets LINK_INTERFACE_LIBRARIES target property empty.
#    The RPATH is set according to the global RPATH settings as set up by FindKDE4Internal.cmake
#    (CMAKE_SKIP_BUILD_RPATH=FALSE, CMAKE_BUILD_WITH_INSTALL_RPATH=FALSE, CMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE)
#    Under Windows it adds a -DMAKE_<name>_LIB definition to the compilation.
#
#  KDE4_ADD_UNIT_TEST (testname [TESTNAME targetname] file1 ... fileN)
#    add a unit test, which is executed when running make test
#    it will be built with RPATH poiting to the build dir
#    The targets are always created, but only built for the "all"
#    target if the option KDE4_BUILD_TESTS is enabled. Otherwise the rules for the target
#    are created but not built by default. You can build them by manually building the target.
#    The name of the target can be specified using TESTNAME <targetname>, if it is not given
#    the macro will default to the <testname>
#    KDESRCDIR is set to the source directory of the test, this can be used with
#    KGlobal::dirs()->addResourceDir( "data", KDESRCDIR )
#
#
#  KDE4_ADD_APP_ICON (SRCS_VAR pattern)
#  adds an application icon to target source list.
#  Make sure you have a 128x128 icon, or the icon won't display on Mac OS X.
#  Mac OSX notes : the application icon is added to a Mac OS X bundle so that Finder and friends show the right thing.
#  Win32 notes: the application icon(s) are compiled into the application
#  There is some workaround in kde4_add_kdeinit_executable to make it possible for those applications as well.
# Parameters:
#  SRCS_VAR  - specifies the list of source files
#  pattern   - regular expression for searching application icons
#  Example: KDE4_ADD_APP_ICON( myapp_SOURCES "pics/cr*-myapp.png")
#  Example: KDE4_ADD_APP_ICON( myapp_KDEINIT_SRCS "icons/oxygen/*/apps/myapp.png")
#
#  KDE4_UPDATE_ICONCACHE()
#    Notifies the icon cache that new icons have been installed by updating
#    mtime of ${ICON_INSTALL_DIR}/hicolor directory.
#
#  KDE4_INSTALL_ICONS( path theme)
#    Installs all png and svgz files in the current directory to the icon
#    directory given in path, in the subdirectory for the given icon theme.
#
#  KDE4_CREATE_HANDBOOK( docbookfile [INSTALL_DESTINATION installdest] [SUBDIR subdir])
#   Create the handbook from the docbookfile (using meinproc4)
#   The resulting handbook will be installed to <installdest> when using
#   INSTALL_DESTINATION <installdest>, or to <installdest>/<subdir> if
#   SUBDIR <subdir> is specified.
#
#  KDE4_CREATE_MANPAGE( docbookfile section )
#   Create the manpage for the specified section from the docbookfile (using meinproc4)
#   The resulting manpage will be installed to <installdest> when using
#   INSTALL_DESTINATION <installdest>, or to <installdest>/<subdir> if
#   SUBDIR <subdir> is specified.
#
#  KDE4_INSTALL_AUTH_ACTIONS( HELPER_ID ACTIONS_FILE )
#   This macro generates an action file, depending on the backend used, for applications using KAuth.
#   It accepts the helper id (the DBUS name) and a file containing the actions (check kdelibs/kdecore/auth/example
#   for file format). The macro will take care of generating the file according to the backend specified,
#   and to install it in the right location. This (at the moment) means that on Linux (PolicyKit) a .policy
#   file will be generated and installed into the policykit action directory (usually /usr/share/PolicyKit/policy/),
#   and on Mac (Authorization Services) will be added to the system action registry using the native MacOS API during
#   the install phase
#
#  KDE4_INSTALL_AUTH_HELPER_FILES( HELPER_TARGET HELPER_ID HELPER_USER )
#   This macro adds the needed files for an helper executable meant to be used by applications using KAuth.
#   It accepts the helper target, the helper ID (the DBUS name) and the user under which the helper will run on.
#   This macro takes care of generate the needed files, and install them in the right location. This boils down
#   to a DBus policy to let the helper register on the system bus, and a service file for letting the helper
#   being automatically activated by the system bus.
#   *WARNING* You have to install the helper in ${LIBEXEC_INSTALL_DIR} to make sure everything will work.
#
#
#
#  A note on the possible values for CMAKE_BUILD_TYPE and how KDE handles
#  the flags for those buildtypes. FindKDE4Internal supports the values
#  Debug, Release, RelWithDebInfo, Profile and Debugfull:
#
#  Release
#          optimised for speed, qDebug/kDebug turned off, no debug symbols, no asserts
#  RelWithDebInfo (Release with debug info)
#          similar to Release, optimised for speed, but with debugging symbols on (-g)
#  Debug
#          optimised but debuggable, debugging on (-g)
#          (-fno-reorder-blocks -fno-schedule-insns -fno-inline)
#  DebugFull
#          no optimization, full debugging on (-g3)
#  Profile
#          DebugFull + -ftest-coverage -fprofile-arcs
#
#
#  The default buildtype is RelWithDebInfo.
#  It is expected that the "Debug" build type be still debuggable with gdb
#  without going all over the place, but still produce better performance.
#  It's also important to note that gcc cannot detect all warning conditions
#  unless the optimiser is active.
#
#
#  This module allows to depend on a particular minimum version of kdelibs.
#  To acomplish that one should use the appropriate cmake syntax for
#  find_package. For example to depend on kdelibs >= 4.1.0 one should use
#
#  find_package(KDE4 4.1.0 REQUIRED)
#
#  In earlier versions of KDE you could use the variable KDE_MIN_VERSION to
#  have such a dependency. This variable is deprecated with KDE 4.2.0, but
#  will still work to make the module backwards-compatible.

   # This macro implements some very special logic how to deal with the cache.
   # By default the various install locations inherit their value from their "parent" variable
   # so if you set CMAKE_INSTALL_PREFIX, then EXEC_INSTALL_PREFIX, PLUGIN_INSTALL_DIR will
   # calculate their value by appending subdirs to CMAKE_INSTALL_PREFIX .
   # This would work completely without using the cache.
   # But if somebody wants e.g. a different EXEC_INSTALL_PREFIX this value has to go into
   # the cache, otherwise it will be forgotten on the next cmake run.
   # Once a variable is in the cache, it doesn't depend on its "parent" variables
   # anymore and you can only change it by editing it directly.
   # this macro helps in this regard, because as long as you don't set one of the
   # variables explicitly to some location, it will always calculate its value from its
   # parents. So modifying CMAKE_INSTALL_PREFIX later on will have the desired effect.
   # But once you decide to set e.g. EXEC_INSTALL_PREFIX to some special location
   # this will go into the cache and it will no longer depend on CMAKE_INSTALL_PREFIX.
