[vtkusers] Static Link VTK

[Alex Malyushytskyy]

Possible problem  - "Static"  Qt build is mostly likely using CRT dlls
unless you manually edited project options. This means you can't link
static VTK (using static CRTs with suck Qt). In fact you still have to
link VTK  as dlls.

I do no think nice solution exists. Some people claim that they were
able to link Qt vs static CRTs. I personally tried this hard with Qt
4.5
and even though my application was running I had some problems with
some cases ( from the top of my head setting specific item in combobox
was giving access violation)

But if you manage to do this and would not have any problem with Qt
you can build static version of vtk and you will get wehat you want.
Otherwise all you can get rid of - Qt dlls. Even though QT is build as
'static' libraries it will be linked against dynamic CRTs which will
force you to provide such CRTs as dependencies and unless you can link
static VTK vs dynamic CRTS ( I am not sure how easy is it) you will
have to build vtk as dlls.
