CMake/Modules/FindQt4.cmake
Alexander Neundorf 03769801ff -make the imported targets feature of FindQt4.cmake fully backwards compatible 
After discussing with Brad and Clinton:
-the namespace for the imported targets is now "Qt4::", tested with Makefiles, Visual Studio and XCode projects
-the imported targets are always created
-if QT_USE_IMPORTED_TARGETS is set to TRUE (it defaults to FALSE), the QT_QTFOO_LIBRARY variables are set to point to these imported
targets, otherwise the old behaviour is used.
-on OSX if Qt has been found as framework, disable QT_USE_IMPORTED_TARGETS, since cmake doesn't handle the framework directory as location of the library correctly

# - 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_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
#
# 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
#
# 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.
#
