# FindQt4
# -------
#
# Finding and Using Qt4
# ^^^^^^^^^^^^^^^^^^^^^
#
# This module can be used to find Qt4.  The most important issue is that
# the Qt4 qmake is available via the system path.  This qmake is then
# used to detect basically everything else.  This module defines a
# number of :prop_tgt:`IMPORTED` targets, macros and variables.
#
# Typical usage could be something like:
#
# .. code-block:: cmake
#
#    set(CMAKE_AUTOMOC ON)
#    set(CMAKE_INCLUDE_CURRENT_DIR ON)
#    find_package(Qt4 4.4.3 REQUIRED QtGui QtXml)
#    add_executable(myexe main.cpp)
#    target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
#
# .. note::
#
#  When using :prop_tgt:`IMPORTED` targets, the qtmain.lib static library is
#  automatically linked on Windows for :prop_tgt:`WIN32 <WIN32_EXECUTABLE>`
#  executables. To disable that globally, set the
#  ``QT4_NO_LINK_QTMAIN`` variable before finding Qt4. To disable that
#  for a particular executable, set the ``QT4_NO_LINK_QTMAIN`` target
#  property to ``TRUE`` on the executable.
#
# Qt Build Tools
# ^^^^^^^^^^^^^^
#
# Qt relies on some bundled tools for code generation, such as ``moc`` for
# meta-object code generation,``uic`` for widget layout and population,
# and ``rcc`` for virtual filesystem content generation.  These tools may be
# automatically invoked by :manual:`cmake(1)` if the appropriate conditions
# are met.  See :manual:`cmake-qt(7)` for more.
#
# Qt Macros
# ^^^^^^^^^
#
# In some cases it can be necessary or useful to invoke the Qt build tools in a
# more-manual way. Several macros are available to add targets for such uses.
#
# ::
#
#   macro QT4_WRAP_CPP(outfiles inputfile ... [TARGET tgt] OPTIONS ...)
#         create moc code from a list of files containing Qt class with
#         the Q_OBJECT declaration.  Per-directory preprocessor definitions
#         are also added.  If the <tgt> is specified, the
#         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
#         the <tgt> are passed to moc.  Options may be given to moc, such as
#         those found when executing "moc -help".
#
#
# ::
#
#   macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
#         create code from a list of Qt designer ui files.
#         Options may be given to uic, such as those found
#         when executing "uic -help"
#
#
# ::
#
#   macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
#         create code from a list of Qt resource files.
#         Options may be given to rcc, such as those found
#         when executing "rcc -help"
#
#
# ::
#
#   macro QT4_GENERATE_MOC(inputfile outputfile [TARGET tgt])
#         creates a rule to run moc on infile and create outfile.
#         Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
#         because you need a custom filename for the moc file or something
#         similar.  If the <tgt> is specified, the
#         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
#         the <tgt> are passed to moc.
#
#
# ::
#
#   macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
#         Create the interface header and implementation files with the
#         given basename from the given interface xml file and add it to
#         the list of sources.
#
#         You can pass additional parameters to the qdbusxml2cpp call by setting
#         properties on the input file:
#
#         INCLUDE the given file will be included in the generate interface header
#
#         CLASSNAME the generated class is named accordingly
#
#         NO_NAMESPACE the generated class is not wrapped in a namespace
#
#
# ::
#
#   macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
#         Create the interface header and implementation files
#         for all listed interface xml files.
#         The basename will be automatically determined from the name
#         of the xml file.
#
#         The source file properties described for
#         QT4_ADD_DBUS_INTERFACE also apply here.
#
#
# ::
#
#   macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname
#                              [basename] [classname])
#         create a dbus adaptor (header and implementation file) from the xml file
#         describing the interface, and add it to the list of sources. The adaptor
#         forwards the calls to a parent class, defined in parentheader and named
#         parentclassname. The name of the generated files will be
#         <basename>adaptor.{cpp,h} where basename defaults to the basename of the
#         xml file.
#         If <classname> is provided, then it will be used as the classname of the
#         adaptor itself.
#
#
# ::
#
#   macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
#         generate the xml interface file from the given header.
#         If the optional argument interfacename is omitted, the name of the
#         interface file is constructed from the basename of the header with
#         the suffix .xml appended.
#         Options may be given to qdbuscpp2xml, such as those found when
#         executing "qdbuscpp2xml --help"
#
#
# ::
#
#   macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
#                                 ts_files ... OPTIONS ...)
#         out: qm_files
#         in:  directories sources ts_files
#         options: flags to pass to lupdate, such as -extensions to specify
#         extensions for a directory scan.
#         generates commands to create .ts (vie lupdate) and .qm
#         (via lrelease) - files from directories and/or sources. The ts files are
#         created and/or updated in the source tree (unless given with full paths).
#         The qm files are generated in the build tree.
#         Updating the translations can be done by adding the qm_files
#         to the source list of your library/executable, so they are
#         always updated, or by adding a custom target to control when
#         they get updated/generated.
#
#
# ::
#
#   macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
#         out: qm_files
#         in:  ts_files
#         generates commands to create .qm from .ts - files. The generated
#         filenames can be found in qm_files. The ts_files
#         must exist and are not updated in any way.
#
#
# ::
#
#   macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... [TARGET tgt])
#         The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
#         This macro is still experimental.
#         It can be used to have moc automatically handled.
#         So if you have the files foo.h and foo.cpp, and in foo.h a
#         a class uses the Q_OBJECT macro, moc has to run on it. If you don't
#         want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
#         #include "foo.moc"
#         in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will
#         scan all listed files at cmake-time for such included moc files and if it
#         finds them cause a rule to be generated to run moc at build time on the
#         accompanying header file foo.h.
#         If a source file has the SKIP_AUTOMOC property set it will be ignored by
#         this macro.
#         If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and
#         INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc.
#
#
# ::
#
#  function QT4_USE_MODULES( target [link_type] modules...)
#         This function is obsolete. Use target_link_libraries with IMPORTED targets
#         instead.
#         Make <target> use the <modules> from Qt. Using a Qt module means
#         to link to the library, add the relevant include directories for the
#         module, and add the relevant compiler defines for using the module.
#         Modules are roughly equivalent to components of Qt4, so usage would be
#         something like:
#          qt4_use_modules(myexe Core Gui Declarative)
#         to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
#         can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the
#         same argument to the target_link_libraries call.
#
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# A particular Qt library may be used by using the corresponding
# :prop_tgt:`IMPORTED` target with the :command:`target_link_libraries`
# command:
#
# .. code-block:: cmake
#
#   target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
#
# Using a target in this way causes :cmake(1)` to use the appropriate include
# directories and compile definitions for the target when compiling ``myexe``.
#
# Targets are aware of their dependencies, so for example it is not necessary
# to list ``Qt4::QtCore`` if another Qt library is listed, and it is not
# necessary to list ``Qt4::QtGui`` if ``Qt4::QtDeclarative`` is listed.
# Targets may be tested for existence in the usual way with the
# :command:`if(TARGET)` command.
#
# The Qt toolkit may contain both debug and release libraries.
# :manual:`cmake(1)` will choose the appropriate version based on the build
# configuration.
#
