Git commit 586cacddb1f5d04f5a792bced560b1c573c452dd by Sami Varanka on 13/08/2026 at 15:21..
Use QT_CONFIG to check whether feature is enabled

Whether a certain feature is enabled should be checked with
QT_CONFIG(<feature_name>). QtGraphs used to check in CMakeLists.txt
if a feature is enabled and define a macro for it. In the source, the
enablement was checked by checking the macro. However, that is a
rather ugly way.

This commit changes them to use QT_CONFIG(<feature_name>),
which is more elegant.
