We are using `Glob` from Go, and the pattern matches [filepath.Match](https://golang.org/pkg/path/filepath/#Match).

```auto
pattern:
	{ term }
term:
	'*' matches any sequence of non-Separator characters
	'?' matches any single non-Separator character
	'[' ['^'] { character-range } ']'
	            character class (must be non-empty)
	c matches character c (c != '*', '?', '\\', '[')
	'\\' c matches character c

character-range:
	c matches character c (c != '\\', '-', ']')
	'\\' c matches character c
	lo '-' hi matches character c for lo <= c <= hi

```

Per the Go docs:

```auto
The pattern may describe hierarchical names such as /usr/*/bin/ed (assuming the Separator is '/'). 

```

So in your specific example `./packages/*/lib/*` should suffice.

Please note that everything must be relative to the work space root directory.

cc @michelle-luna we could probably just snag that right out of the Go docs and put it in ours since its the source of truth.
