Modules/FindQt4.cmake

   1 # - Find QT 4
   2 # This module can be used to find Qt4.
   3 # The most important issue is that the Qt4 qmake is available via the system path.
   4 # This qmake is then used to detect basically everything else.
   5 # This module defines a number of key variables and macros.
   6 # The variable QT_USE_FILE is set which is the path to a CMake file that can be included
   7 # to compile Qt 4 applications and libraries.  It sets up the compilation
   8 # environment for include directories, preprocessor defines and populates a
   9 # QT_LIBRARIES variable.
  10 #
  11 # Typical usage could be something like:
  12 #   find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml)
  13 #   include(${QT_USE_FILE})
  14 #   add_executable(myexe main.cpp)
  15 #   target_link_libraries(myexe ${QT_LIBRARIES})
  16 #
  17 # The minimum required version can be specified using the standard find_package()-syntax
  18 # (see example above).
  19 # For compatibility with older versions of FindQt4.cmake it is also possible to
  20 # set the variable QT_MIN_VERSION to the minimum required version of Qt4 before the
  21 # find_package(Qt4) command.
  22 # If both are used, the version used in the find_package() command overrides the
  23 # one from QT_MIN_VERSION.
  24 #
  25 # When using the components argument, QT_USE_QT* variables are automatically set
  26 # for the QT_USE_FILE to pick up.  If one wishes to manually set them, the
  27 # available ones to set include:
  28 #                    QT_DONT_USE_QTCORE
  29 #                    QT_DONT_USE_QTGUI
  30 #                    QT_USE_QT3SUPPORT
  31 #                    QT_USE_QTASSISTANT

  54 #                    QT_USE_QTDECLARATIVE
  55 #
  56 #  QT_USE_IMPORTED_TARGETS
  57 #        If this variable is set to TRUE, FindQt4.cmake will create imported
  58 #        library targets for the various Qt libraries and set the
  59 #        library variables like QT_QTCORE_LIBRARY to point at these imported
  60 #        targets instead of the library file on disk. This provides much better
  61 #        handling of the release and debug versions of the Qt libraries and is
  62 #       also always backwards compatible, except for the case that dependencies
  63 #       of libraries are exported, these will then also list the names of the
  64 #       imported targets as dependency and not the file location on disk. This
  65 #       is much more flexible, but requires that FindQt4.cmake is executed before
  66 #       such an exported dependency file is processed.
  67 #
  68 # There are also some files that need processing by some Qt tools such as moc
  69 # and uic.  Listed below are macros that may be used to process those files.
  70 #
  71 #  macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
  72 #        create moc code from a list of files containing Qt class with
  73 #        the Q_OBJECT declaration.  Per-direcotry preprocessor definitions
  74 #        are also added.  Options may be given to moc, such as those found
  75 #        when executing "moc -help".
  76 #
  77 #  macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
  78 #        create code from a list of Qt designer ui files.
  79 #        Options may be given to uic, such as those found
  80 #        when executing "uic -help"
  81 #
  82 #  macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
  83 #        create code from a list of Qt resource files.
  84 #        Options may be given to rcc, such as those found
  85 #        when executing "rcc -help"
  86 #
  87 #  macro QT4_GENERATE_MOC(inputfile outputfile )
  88 #        creates a rule to run moc on infile and create outfile.
  89 #        Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
  90 #        because you need a custom filename for the moc file or something similar.
  91 #
  92 #  macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
  93 #        This macro is still experimental.
  94 #        It can be used to have moc automatically handled.
  95 #        So if you have the files foo.h and foo.cpp, and in foo.h a
  96 #        a class uses the Q_OBJECT macro, moc has to run on it. If you don't
  97 #        want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
  98 #        #include "foo.moc"
  99 #        in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
 100 #        scan all listed files at cmake-time for such included moc files and if it finds
 101 #        them cause a rule to be generated to run moc at build time on the
 102 #        accompanying header file foo.h.
 103 #        If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.
 104 #
 105 #  macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
 106 #        create a the interface header and implementation files with the

 109 #
 110 #  macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
 111 #        create the interface header and implementation files
 112 #        for all listed interface xml files
 113 #        the name will be automatically determined from the name of the xml file

 116 #        create a dbus adaptor (header and implementation file) from the xml file
 117 #        describing the interface, and add it to the list of sources. The adaptor
 118 #        forwards the calls to a parent class, defined in parentheader and named
 119 #        parentclassname. The name of the generated files will be
 120 #        <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
 121 #        If <classname> is provided, then it will be used as the classname of the
 122 #        adaptor itself.
 123 #
 124 #  macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
 125 #        generate the xml interface file from the given header.
 126 #        If the optional argument interfacename is omitted, the name of the
 127 #        interface file is constructed from the basename of the header with
 128 #        the suffix .xml appended.
 129 #        Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

 140 #        The qm files are generated in the build tree.
 141 #        Updating the translations can be done by adding the qm_files
 142 #        to the source list of your library/executable, so they are
