# Locate Qt include paths and libraries
# This module defines
# QT_INCLUDE_DIR, where to find qt.h, etc.
# QT_LIBRARIES, the libraries to link against to use Qt.
# QT_DEFINITIONS, definitions to use when compiling code that uses Qt.
# QT_FOUND, If false, don't try to use Qt.
#if you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE
# also defined, but not for general use are
# QT_MOC_EXECUTABLE, where to find the moc tool.
# QT_UIC_EXECUTABLE, where to find the uic tool.
# QT_QT_LIBRARY, where to find the Qt library.
# QT_QTMAIN_LIBRARY, where to find the qtmain library. This is only required by Qt3 on Windows.
# These are around for backwards compatibility
# they will be set
# QT_WRAP_CPP, set true if QT_MOC_EXECUTABLE is found
# QT_WRAP_UI set true if QT_UIC_EXECUTABLE is found
