GN copy maintaining directory structure ("cp -r")

[brian.a...@discordapp.com]

Hello,

Is it feasible to use a copy() step in GN to copy the outputs from another step to a new directory, but maintaining directory structure relative to some part of the source directory? E.g., can I copy /build/gen/blah/foo/bar/baz to /build/dest/foo/bar/baz and /build/gen/blah/foo/bar/qux/quux to /build/dest/foo/bar/qux/quux? I thought the answer might involve rebase_path, but no incantation I can come up with seems to do this, and I've tried quite a few now.

Thanks!

Brian

GN's copy() step being able to copy directories is considered a bug. https://crbug.com/855747 has some words on why. So you shouldn't try and use it for this purpose.

I should have clarified, I have all the source files from get_target_outputs(), and I'm looking to transform the outputs according to this strategy, so it's not a blind recursive copy.

The "copy" used here[1] might be useful. (Note the .framework is a directory.)
