[Insight-users] building errors when using itk::WatershedImageFilter

[Dan Mueller]

Hi orientation f,

Can you please post the CMake file you are using? (Are you using CMake?)

It seems you have not included ITKAlgorithms in the TARGET_LINK_LIBRARIES.

eg. TARGET_LINK_LIBRARIES( ITKIO ITKAlgorithms )

Regards, Dan
