cargo vendor fetches incomplete crate

[jamin-aws-ospo]

Problem

I tried to configure https://github.com/jpeddicord/askalono for building offline.

I clone the repo, change to the cli folder, and issue: cargo vendor. I then create the .cargo/config as instructed. However, attempting an offline build with cargo build --offline results in this error:

error: failed to run custom build command for `zstd-sys v1.6.0+zstd.1.5.0`

Caused by:
  process didn't exit successfully: `/home/jamin/tmp/askalono/cli/../target/debug/build/zstd-sys-f29cef9d59229dd4/build-script-build` (exit status: 101)
  --- stderr
  thread 'main' panicked at 'Folder 'zstd/lib' does not exists. Maybe you forgot to clone the 'zstd' submodule?', /home/jamin/tmp/askalono/cli/vendor/zstd-sys/build.rs:180:13
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
warning: build failed, waiting for other jobs to finish...
error: build failed

The cli/vendor/zstd-sys folder is indeed missing the zstd/lib folder.

However, checking the same crate version shows that the folder is present in the crate.

Steps

1. git clone https://github.com/jpeddicord/askalono
2. cd askalono/cli
3. cargo vendor
4. create the suggested ../.cargo/config
5. cargo build --offline

This is an issue with zstd-sys v1.6.0. It had an exclude pattern which prevented the zstd directory from being included. You'll need to update to a newer version of zstd (which appears like you already have).

Closing as a duplicate of #9555.
