Everything you need is built into Visual Studio.
SharePoint farm solutions are packaged as a .wsp file. This file contains all of the assets related to your solution including the feature files, DLLs, etc.. When you build a farm solution in Visual Studio, every time you deploy locally the .wsp file is added to your \bin\debug or \bin\release folder, depending on which mode your in.
Grab that and deploy it to your other SharePoint environment using the PowerShell commands Add-SPSolution then Install-SPSolution. http://technet.microsoft.com/en-us/library/ff607552(v=office.15).aspx http://technet.microsoft.com/en-us/library/ff607534(v=office.15).aspx
Deploying the SharePoint solution this way ensures everything in your solution is placed correctly on all servers in your production environment. You should never need to manually add files to the 15 hive (SharePoint Root) handle DLLs manually
