# Rewrite absolute SDL load commands in the Companion executable to the bundled copies.

# Companion used to run fixup_bundle, which walked every Mach-O in the bundle and rewrote all
|
|
# of their load commands in one pass. That was replaced by qt_deploy_runtime_dependencies,
|
|
# which runs *before* the SDL install(FILES) steps, and by an install_name_tool -id call that
|
|
# only fixes each dylib's own id. Nothing in that chain guarantees the executable actually
|
|
# references the SDL copies sitting in Contents/Frameworks, so make it explicit here.
