[Rtk-users] RTK helloworld

[Julien Jomier]

Dear Padraig,

When you say "built and is working but I have hundreds of errors" do you 
mean that you have successfully compiled and linked the example? It 
seems that your example cannot find the ITK libraries. Are you building 
ITK and RTK using BUILD_SHARED_LIBS to ON in CMake?
