Building a library

[konsumlamm]

It seems to me that there is no way to just build a library with nimble (without creating a custom task), to see if it compiles. nimble build expects there to be a bin key (i.e. an executable). I think it would be nice to make nimble build also compile libraries.

I really like this idea and have thus just created an issue wit h some more details on how to go with it (#1014 Allow Dynamic Library Target)
