[vtkusers] VTK deployment with static libraries on Mac (and in Qt Creator)

[David Gobbi]

Hi Richard,

It is possible to build dynamically-linked applications with Qt and VTK,
and to share such applications.  On the Mac, the Qt libraries become part
of the app bundle.  I do not know how to do this with Qt Creator, but there
should definitely be Qt experts around who know how to do it.  Maybe not on
the VTK list, however, since I don't think that many of us here use Qt
Creator.

There are two strong reasons for using dynamic linking with Qt:
1) it allows you to use the Qt binaries from the Qt download site.
2) it allows you to use the Qt LGPL license without releasing your code

Reason (2) is important.  If you use static Qt libraries, then you must
either pay for a Qt license or else release your own code as LGPL or a
compatible open-source license.

 - David
