Built qtcurve but can't configure/change dot qtcurve theme or open a dialog as in plasma 5

As the title says, I built using the latest source but now I can’t figure a way to change the theme… Any ideas?. I should clarify that I can change to qtcurve in kde settings but the dialog to configure the theme is not there. I’ve looked in the qtcurve hidden home directory in config and there’s nothing there. There’s a breeze. qtcurve theme in usr local I think. but changing that seems to do nothing either.
