Hi Wagner,

I am using VTK on Windows 7, with MinGW 4.4.0.  I have successfully  
built the libraries in both shared and static form.  I don't recall  
seeing any issues of the kind you mention.  I do see one difference in  
our setups, though.  I downloaded and installed MinGW separately, i.e.  
not using the Nokia-supplied version.  You might try that.  Another  
possibly unrelated piece of info comes to mind.  I was having trouble  
building Qt-4.6.3 from the source code that comes with the SDK (this  
was 2010.04) and was advised by a Nokia bug-killer that it is not in  
general possible to rebuild Qt from those sources - instead one needs  
to start from the source distribution package.

In any case, I can attest to the fact that MinGW works well for  
building both VTK and Qt, without any need for Cygwin.

If someone who knows a lot more about Cmake than I do can suggest any  
of my build files I could send you that might help, I'd be happy to  
oblige.

Cheers
Gib
