Hi, 

I understand the reasoning, but there's pain on the other side too: As soon as you integrate QML like Qt Creator does, you're likely hit by problems. Just look at the list of linked bugs in Qt Creator under

https://bugreports.qt-project.org/browse/QTBUG-17529

Absolute paths that work for the rest of Qt break for QML ... The counter measure is 'normalizing' paths handed over to QtDeclarative/QtQml, but there's not even a Qt API for it. Now you could argue that Qt Creator is somehow special, but Matthias isn't the first external one complaining about this, there have been others before too ...

So all in all, I think the current strict checking does more harm than good. Alternatives I see are:

 - normalizing paths handed over via public API (this is what my patch does)
 - change error into a warning
 - just check for file names, not directories
 - get rid of the check altogether, and maybe warn about potential problems in the Qt Creator IDE

PS: Is there any other interpreter / compiler being so strict about file casing like we are? I don't think I've encountered one ...
