[ITK] [ITK-users] VS input library files

[Francois Budin]

Hello Gib,

It seems that you built ITK with the VTK bridge (CMake option
Module_ITKVtkGlue), and you probably built VTK with Qt support. It is
surprising that the Qt libraries do not match the Qt version on your
computer. Did you build VTK on a different computer?
To be able to compile any project that you link against ITK, CMake needs to
know of all the dependencies of ITK. Because ITK is still using the CMake 2
paradigm (project based dependencies, vs CMake 3 that is target based), if
you do not specify which module needs to be loaded, all the dependencies
will be added to all your targets.
If you want to limit the number of dependencies, you can specify the ITK
components that are loaded by CMake:
find_package(ITK COMPONENTS {add required components here} )

Another solution is to rebuild ITK without VTK support.
Hope this helps,
Francois
