It isn't related to that project, because the goals are different. QtComponents for Fremantle is about enabling applications written using Harmattan QtComponents to run unaltered on Fremantle using Harmattan UX. Hildon QtComponents is about enabling developers to create applications with Hildon UX using QML. The component names and properties are kept as similar to Harmattan QtComponents as possible for familiarity, but there is very little code shared between the two projects (only the PageStack component, I think). Hildon QtComponents does not depend on QtComponents for Fremantle.
