Never hit this problem with _static_ libs in all the years so far, so new for
me ;)
((I somehow would have assumed that symbols from static libs are namespaced on
linking, especially as noone seems to have guarded such linking in any other
way, also did not catch my attention elsewhere yet. Possibly because people
were not aware that libQtUiTools is a static and not a shared lib, this fact
being hidden behind the var ${QT_QTUITOOLS_LIBRARY}))
So, still wondering what the (most) platform-independent fix can be from our
side to this problem?
