Why does FindQt4.cmake add a link dependency of QtScript to QtUiTools?

Unfortunately, it's required. QtUiTools depends on QtScript. It's an 
indirect dependency.

However, QtUiTools is a static library. That means it's up to the final 
applications to link to all of its dependencies. Hence, the line above.

In other words: your code *does* require QtScript.
