The POST_BUILD steps copy generated artifacts into ${CMAKE_SOURCE_DIR}/node, which mutates the source tree and can break read-only source checkouts or multi-config/out-of-tree builds (multiple build dirs racing to overwrite the same files). Prefer copying into an install/package staging directory (e.g., via install(FILES ...) + cpack, or a dedicated package_node target that writes under ${CMAKE_CURRENT_BINARY_DIR}) and have the publish step pull from that output.

These POST_BUILD commands write build outputs into ${CMAKE_SOURCE_DIR}/node, which mutates the source tree during a build and can fail in read-only source checkouts (or cause dirty working trees in CI). Consider copying into the build tree and/or making this step opt-in (e.g., behind an option or an explicit install/packaging target).
