Hello,
as Dzenan suggests in the mailing list, i write my question here to possibly get more attention or answers 🙂

Hello Norbert,
A few things to try:
- Make sure the ITK build completed successfully (so the targets exist)
- Use a shorter path for the ITK and VTK build tree. Visual Studio has path length issues.
- Check in with the MITK folks.
HTH,
Matt

Hey Matt,
thanks for your quick response!
- ITK build completed successfully
> Use a shorter path for the ITK and VTK build tree. Visual Studio has path length issues.
- well, in my opinion its short 😃 also building & running the ITK Hello World works
> Check in with the MITK folks.
Well, they’re not as quick as you are. I just want to make sure that i do not have to make an extra build configuration for ITK when using it with MITK.

Were you able to figure out this issue?
I am having a similar problem with gdcm.
I think the solution might be:
[http://itk-users.7.n7.nabble.com/ITK-users-Problem-using-CMAKE-including-ITK-VTK-and-GDCM-td38933.html](http://itk-users.7.n7.nabble.com/ITK-users-Problem-using-CMAKE-including-ITK-VTK-and-GDCM-td38933.html)
or in my case i needed to specify the gdcm directory in the cmake files
