You seem to be linking against a release version of ITK. It might make sense if you “installed” ITK. If you switch your HelloWorld project from Debug to Release or RelWithDebInfo mode, it should link correctly.

Best way is to configure HelloWorld using CMake and point to build directory of ITK. If you built ITK in both Debug and Release modes, your project should compile and link in those modes without problem.
