[vtkusers] Static Link VTK

[Mehdi Esteghamatian]

Dear Alex,

Thanks for the response. I did not know about CRTs I am not too sure it can
affect the static compilations.

Is it recommended for Win32 machines because I am running it on Vista and
MSVC 2010.

I will probably clean up everthing do it again see if I can understand what
is going on :)
Cheers,
Mehdi
