From 173daad58de172ad5edbbf72117b5597c7339007 Mon Sep 17 00:00:00 2001

Subject: ExternalProject: Move more internal commands out of main file
The commands moved to shared_internal_commands.cmake
will soon be used directly by FetchContent, which cannot
always include the full ExternalProject.cmake file (e.g. it may
be used in CMake script mode).
Issue: #21703
