library crates to package in the @code{package} phase. Specified crates are
packaged from left to right, in case there's dependency among them. For
example, specifying @code{''("pcre2-sys" "pcre2")} will package
@code{"pcre2-sys"} first and then @code{"pcre2"}.
@code{"pcre2-sys"} first and then @code{"pcre2"}. Parameter
@code{#:cargo-install-paths} (default: @code{''()}) allows specifying paths of
binary crates to install in the @code{install} phase, @code{''("crates/atuin")},
for example.
