Subject: [PATCH 2/2] COMP: Name ITK modules, not targets, in find_package
 COMPONENTS

find_package(ITK COMPONENTS ...) takes module names; the ITK::...Module
spellings are target names. ITKImageBase, ITKAnisotropicSmoothingModule,
and ITKImageIntensityModule are not modules, so ITKModuleAPI.cmake stops
with "No such module".

List ITKIOImageBase, ITKAnisotropicSmoothing, ITKImageIntensity, and the
ITKImageIO factory meta-module, and link ITK::ITKImageIO as the ITK 6
migration guide shows. Built against ITK main, the executable links the
same 52 ITK libraries and registers the same 24 ImageIO factories as the
explicit-target form, and its output is byte-identical.
