Lookup path
Syntax
lookup-path =
<identifier [/identifier ]...>
A lookup path is an identifier with an optional path suffix that resolves to a path value if the identifier matches a search path entry.
The value of a lookup path is determined by builtins.nixPath.
See builtins.findFile for details on lookup path resolution.
