[vtkusers] QT+VTK+ITK 64bit version

[Gib Bogle]

By the way it's quite feasible to have both 32bit and 64bit Qt, ITK and VTK installations on your system.  Just install in different suitably-named directories, and make sure the relevant environmental variables (e.g. PATH) are set correctly.

I assumed that you didn't have Makefile, and was just guessing at a cause.

I believe that if you build Qt from the x86 command prompt, you will get 32bit libraries.  You need to build in the x64 command prompt to get 64bit libraries - otherwise there is nothing to tell the compiler to do a 64bit build.  This is my understanding, and I hope somebody will correct me if I'm wrong.

Similarly when you build ITK and VTK (or any other 64bit targets) with cmake, you have to specify Visual Studio 10 Win64 as the generator.

Hi Gib,

I did as John said and it seems building after jom.exe. But I used the
default command prompt (x86). Is that wrong??

I already have a project using VTK+ITK+QT, so I guess I need to re-configure
& re-install vtk and itk using vs2010 x64 and reconfigure my project??
