# - Find QT 4 # 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 key variables and macros. # The variable QT_USE_FILE is set which is the path to a CMake file that can be included # to compile Qt 4 applications and libraries. It sets up the compilation # environment for include directories, preprocessor defines and populates a # QT_LIBRARIES variable. # # Typical usage could be something like: # find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED ) # include(${QT_USE_FILE}) # add_executable(myexe main.cpp) # target_link_libraries(myexe ${QT_LIBRARIES}) # # The minimum required version can be specified using the standard find_package()-syntax # (see example above). # For compatibility with older versions of FindQt4.cmake it is also possible to # set the variable QT_MIN_VERSION to the minimum required version of Qt4 before the # find_package(Qt4) command. # If both are used, the version used in the find_package() command overrides the # one from QT_MIN_VERSION. # # When using the components argument, QT_USE_QT* variables are automatically set # for the QT_USE_FILE to pick up. If one wishes to manually set them, the # available ones to set include: # QT_DONT_USE_QTCORE # QT_DONT_USE_QTGUI # QT_USE_QT3SUPPORT # QT_USE_QTASSISTANT # QT_USE_QAXCONTAINER # QT_USE_QAXSERVER # QT_USE_QTDESIGNER # QT_USE_QTMOTIF # QT_USE_QTMAIN # QT_USE_QTMULTIMEDIA # QT_USE_QTNETWORK # QT_USE_QTNSPLUGIN # QT_USE_QTOPENGL # QT_USE_QTSQL # QT_USE_QTXML # QT_USE_QTSVG # QT_USE_QTTEST # QT_USE_QTUITOOLS # QT_USE_QTDBUS # QT_USE_QTSCRIPT # QT_USE_QTASSISTANTCLIENT # QT_USE_QTHELP # QT_USE_QTWEBKIT # QT_USE_QTXMLPATTERNS # QT_USE_PHONON # QT_USE_QTSCRIPTTOOLS # QT_USE_QTDECLARATIVE # # QT_USE_IMPORTED_TARGETS # If this variable is set to TRUE, FindQt4.cmake will create imported # library targets for the various Qt libraries and set the # library variables like QT_QTCORE_LIBRARY to point at these imported # targets instead of the library file on disk. This provides much better # handling of the release and debug versions of the Qt libraries and is # also always backwards compatible, except for the case that dependencies # of libraries are exported, these will then also list the names of the # imported targets as dependency and not the file location on disk. This # is much more flexible, but requires that FindQt4.cmake is executed before # such an exported dependency file is processed. # # There are also some files that need processing by some Qt tools such as moc # and uic. Listed below are macros that may be used to process those files. #

# macro QT4_WRAP_CPP(outfiles inputfile … OPTIONS …) # create moc code from a list of files containing Qt class with # the Q_OBJECT declaration. Per-direcotry preprocessor definitions # are also added. 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 ) # 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. # # macro QT4_AUTOMOC(sourcefile1 sourcefile2 … ) # 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 the # 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. # # macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename) # create a the interface header and implementation files with the # given basename from the given interface xml file and add it to # the list of sources. # To disable generating a namespace header, set the source file property # NO_NAMESPACE to TRUE on the interface file. # To include a header in the interface header, set the source file property # INCLUDE to the name of the header. # To specify a class name to use, set the source file property CLASSNAME # to the name of the class. # # macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile … ) # create the interface header and implementation files # for all listed interface xml files # the name will be automatically determined from the name of the xml file # To disable generating namespace headers, set the source file property # NO_NAMESPACE to TRUE for these inputfiles. # To include a header in the interface header, set the source file property # INCLUDE to the name of the header. # To specify a class name to use, set the source file property CLASSNAME # to the name of the class. # # 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.
