+# 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
