Version: 5.3rc04
clang-14
FreeBSD 13.1

Start with BasicRegionGrowing/Code.cxx from the linked BasicRegionGrowing example and reproduce the build with the reported ITK, VTK, clang-14, and FreeBSD versions. Check the reported API and undeclared-identifier errors, then verify that the example compiles without those diagnostics.
