DUB library prefix - rules ?

quoted from the website:

I must be blind but I can't find the code that adds the 'lib' 
prefix on GitHub. I need to check something:

Is it correct to say that
- under Macosx and Linux, the 'lib' prefix is added if target is 
a library.
- under Windows, nothing is added and targetName is used as it.

Otherwise, if you have the link with the matching line highlihted 
on GH.
