[Insight-developers] 4GB images on windows

[Jean-Christophe Fillion-Robin]

Looking at this in more details, within the ITK CMakeLists, I can observe
that the option "ITK_USE_64BITS_IDS" is exposed only if
ITKV3_COMPATIBILITY  is disabled. See [1]

Considering  that Slicer builds ITK with  ITKV3_COMPATIBILITY enabled, will
that cause any issues ?

Note: ITKV3_COMPATIBILITY is currently required for some extension, if
needed I guess we could suggest extension maintainer to update their code
...

Thanks
Jc
