The process is the same for iTunes 12 as it was for previous versions.  Note that some of the "guidance" available online describes how to move your media from one computer to another without replicating the complete library structure and content.  Doing the latter is essential if you want to preserve playlists, ratings, play counts, etc.
As long as your library is in the standard structure (typically under C:\Users\username\Music\iTunes), with all your media contained within the iTunes Media folder in a structure like this:
you can copy the complete iTunes folder from your old computer to the equivalent location on the new one.  Then, to make sure you're connecting to the right iTunes library database, hold down SHIFT when you start iTunes on the new computer and when you see this prompt:
click on Choose Library..., navigate to the iTunes folder you just copied, select the iTunes Library.itl folder you'll find there, and click Open.
If your library is not structured as above - and particularly if some or all of your media is not contained in the iTunes Media folder - see turingtest2's user tip on Make a split library portable for the steps that will modify the layout of your library to make it so.
This method results in a complete replica of the library that was on your old computer on the new one - this means that your iDevices will sync correctly on the new machine without having to make any further changes,
