# - 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. 
# First is QT_USE_FILE which is the path to a CMake file that can be included 
# to compile Qt 4 applications and libraries.  By default, the QtCore and QtGui 
# libraries are loaded. This behavior can be changed by setting one or more 
# of the following variables to true before doing INCLUDE(${QT_USE_FILE}):
#                    QT_DONT_USE_QTCORE
#                    QT_DONT_USE_QTGUI
#                    QT_USE_QT3SUPPORT
#                    QT_USE_QTASSISTANT
#                    QT_USE_QTDESIGNER
#                    QT_USE_QTMOTIF
#                    QT_USE_QTMAIN
#                    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_PHONON
#
# The file pointed to by QT_USE_FILE will set up your compile environment
# by adding include directories, preprocessor defines, and populate a
# QT_LIBRARIES variable containing all the Qt libraries and their dependencies.
# Add the QT_LIBRARIES variable to your TARGET_LINK_LIBRARIES.
#
# Typical usage could be something like:
#   FIND_PACKAGE(Qt4)
#   SET(QT_USE_QTXML 1)
#   INCLUDE(${QT_USE_FILE})
#   ADD_EXECUTABLE(myexe main.cpp)
#   TARGET_LINK_LIBRARIES(myexe ${QT_LIBRARIES})
#
#
# 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.  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] )
#        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 is the basename of the xml file.
#
#  macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] )
#        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.
#
#  macro QT4_CREATE_TRANSLATION( qm_files sources ... ts_files ... )
#        out: qm_files
#        in:  sources ts_files
#        generates commands to create .ts (vie lupdate) and .qm
#        (via lrelease) - files from 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.
