# - 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:
#                    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

#        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.
#
#  macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
#        create the interface header and implementation files

#        To disable generating namespace headers, set the source file property 
#        NO_NAMESPACE to TRUE for these inputfiles.
#
#  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.
