I did a google search for that particular error message. There were a number of hits, but they all seemed to be concerned with misusing the Qt4 libraries on Unix, e.g., forgetting to use #include <QApplication> But we obviously do that (see include/qt.h), and we have no such trouble on Linux so I don't think our code misuses Qt4 at all. Therefore, I have no idea why you are getting this run-time error message on Cygwin. The only faint possibility I can think of is you might need to install some additional Qt4 component. But I am virtually positive that would generate a cmake WARNING message so I suggest you double check the cmake command output (cmake.out) for any such messages concerning Qt and also check your Qt4 installation for consistency, i.e. all versions the same, no additional Qt4 installations interfering, etc. If those checks don't give you any ideas, then you should also obviously check on the Cygwin mailing list although my google searching above found nothing Cygwin-specific about the above error message.
