Subject: [PATCH] COMP: Drop dead cmake_minimum_required + standalone wrapper
 from ingests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four already-merged remote-module ingests still carry their
upstream-original boilerplate at the top of their module CMakeLists:

  - cmake_minimum_required(VERSION X.Y.Z) — redundant; ITK's top-level
    CMakeLists pins a higher minimum.
  - if(NOT ITK_SOURCE_DIR) ... find_package(ITK) ... else()
    itk_module_impl() endif() — dead code in-tree because
    ITK_SOURCE_DIR is always defined.

Strip both from:

  Modules/Filtering/AnisotropicDiffusionLBR
  Modules/Filtering/Cuberille
  Modules/Filtering/LabelErodeDilate
  Modules/Registration/Montage

Lines that had effect inside the in-tree else() branch
(set(ITK_DIR ${CMAKE_BINARY_DIR}) on AnisotropicDiffusionLBR and
Montage) are preserved unconditionally.

The other four merged ingests (GenericLabelInterpolator, MGHIO,
FastBilateral, MeshNoise) were already cleaned up during their
respective ingest PRs.

Matches the v4 ingest-pipeline rules now codified in PR #6204
(sanitize-history.py:patch_drop_cmake_minimum_required and
:patch_standalone_build_guard); future ingests will not introduce
this idiom.
