[ITK] Build Error MITK 2016.11: ITK targets not defined

[Norbert Martin Lang]

Hello,

I already posted this on the MITK mailing list but still got no answer.
So I will try it here.

I tried to build MITK (v2016.11) from source with external VTK (v8.1.0)
and external ITK (v4.13.0) on Windows 10 with MVSC 15 2017 Win64. ITK,
VTK and Qt is built with the same compiler (and so on) and works fine
running standalone.

Additionaly i added the paths to the .dll's to the Windows system path
before.

So, the MITK build went fine (except for a few warnings) until it
searches for ITK (i suppose it doesnt reached VTK settings); it shows
following error:

So, somehow it cannot include all the ITK libraries. Path to
ITKConfig.cmake is well set as i see. Any ideas how to solve this? Is
this a problem related to the CMake files of MITK or should i apply some
additional configuration to the ITK build?

Thanks
