[Insight-users] an LNK2001 ERROR

[Luis Ibanez]

Hi Zhang,

You are missing to link with the ITKNumerics library.

Please replace the line

    TARGET_LINK_LIBRARIES(HelloWorld ITKCommon ITKIO)

with the line

    TARGET_LINK_LIBRARIES(HelloWorld ITKNumerics ITKIO ITKCommon)



Regards,


     Luis
