+# This file sets up Qt for CMake. When Qt6 was setup successfully, 'Qt6_FOUND'

+# 'Qt5_FOUND' will be set. If both Qt6 and Qt5 are not found, it will stop the
+# configuration and show an error message.
+# If either Qt6 or Qt5 is found, it will set QtLibs to the corresponding Qt
+# libraries, e.g., Qt5Core, Qt5Gui, Qt5Widgets, Qt5OpenGL, Qt5Xml, etc.
+#
+# To use Qt in your program, you only need to include this file and specifying
