# RefixupMacOS.cmake
# Now that we don't use BundleUtilities and instead use GET_RUNTIME_DEPENDENCIES,
# the binaries that are built all have absolute path library load commands.
# What we need to do here is update all the paths for _the runtime dependencies
# that we installed into the bundle_ to live in @rpath, with Python getting
# special treatment in that it lives in @rpath/Frameworks.
# Make sure GLOB_RECURSE doesn't follow symlinks
