[Insight-users] I'm New... linking issue under MS Visual Studio 8. Am using CMake

Hi Dan,  

Thanks for your reply.

Yes.  Adding ITKIO to the TARGET_LINK_LIBRARIES statement in CMakeLists.txt
fixed the issue.

Is there someplace I can find a list of valid CMake directives for ITK?  

Or, is there someway I could have discovered that ITKIO was the label to add
to TARGET_LINK_LIBRARIES for the classes I was using?  I wonder if I will
come across this problem as I explore more of the ITK library.

Or... is there some "ITK_LINK_ALL" label that I could have tried?  If so, it
might be a little slower linking, but would have saved me a lot of time
otherwise.  This might be an inelegant solution, but it could save others
some "banging head against table" time.

Best -

Perry
