[Insight-users] About linking when using -lz

[Luis Ibanez]

Hi 李健

Modify the CMake line:

TARGET_LINK_LIBRARIES(testImage ${ITK_LIBRARIES} ${IMAGE_LIBRARY})

to make it:

TARGET_LINK_LIBRARIES(testImage ${ITK_LIBRARIES} ${IMAGE_LIBRARY} z )

That should do the trick, if your library "libz.a" is already in the
library path.


    Regards,


        Luis
