      Qtbase example compile failed in case gui module is enabled and opengl is disabled (see [1] for details):

       I think the bug was introduced by commit 329385a5d53f7c20d25b8b492acdd45a5c5ff194 which claimed (incorrect/incomplete) to fix QTBUG-57255. I believe QTBUG-57255 is instead a duplicate of QTBUG-60488, fixed by commit 18d49808db46add078d9d4bcffaac5361d5c7269.

      Fixed by re-adding dependency of examples/opengl compile only in case opengl is enabled.
