[Insight-users] [ITK Community] QtITK Bluiding problem (linking problem) please help

Fri Nov 8 12:25:28 EST 2013

Hi Adem,

The CMakeLists.txt needs to be updated.  The link_libraries command is
deprecated in favor of target_link_libraries.  This should come after
the add_executable call.  More work may be required.

Thanks,
Matt
