CMake/Modules/FindQt4.cmake
Stephen Kelly 4d5230d1d8 Only add existing targets to the Qt4 target depends properties. 
Qt can be configured in ways which disable certain modules. Make
sure we don't fail on that.

# - 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 REQUIRED QtCore QtGui QtXml)
# 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.
#
# Note that if using IMPORTED targets, the qtmain.lib static library is
# automatically linked on Windows. 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_INCLUDE_DIRS_NO_SYSTEM
# If this variable is set to TRUE, the Qt include directories
# in the QT_USE_FILE will NOT have the SYSTEM keyword set.
#
# 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-directory 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.
#
# You should have a look on the AUTOMOC property for targets to achieve the same results.
#
# 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.
#
# 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 exists and are not updated in any way.
#
# function QT4_USE_MODULES( target [link_type] modules...)
# 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.
#
