Ah yes... It did not even occur to me that someone trying to install a Qt IDE would not have installed Qt first and adjusted its environment variables... Maybe I become too geeky over the last few years to remember what newbies expect...

The big problem of bundling Qt dlls with Edyuk is that Edyuk relies on QLibraryInfo to get some informations (such as default qmake path, headers location to build completion db, ...) and bundling libs would probably lead to Edyuk being fed with wrong informatins which would affect the user experience way worse than having to setp up a proper Qt environment in the first place...
