While building the current MITK with ITK 3.18 as a Release works fine, building it as a Debug produces as error:
itk3180\code\common\itkNonUniformBSpline.h(83) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const std::vector<_Ty>' (or there is no acceptable conversion)
resulting in the mitkIGT.lib not being build.
As far as I can trace the problem through the macros it is located in
itkMacro.h line 237
which is only compiled for a Debug build.
