Yes, this is supposed to be an easy task - but you're not supposed to hard-code paths. You should use the native APIs on win/mac, and an enviroment variable on most newer unix-like. Of course, Qt helps you do this cross-platform.

Follow Tibur's suggestion and use QSettings if it's configuration data for your Qt app. You can also get the config directory by using the appropriate QT api.

QT5: QStandardPaths::writableLocation(QStandardPaths::GenericDataLocation)
