How can I cross-compile Scala versions that support different core library APIs?

I'm building a library I want to support Scala 2.12 and 2.13 targets. There are a few differences between these versions that are just incompatible, meaning I need different code for a few areas between the 2 versions.

For example 2.12.x Builder (abstract class) requires you to implement a method '+='. In 2.13.x '+=' is now final and you need to implement method 'addOne'. Argh. A few things like that.

What's the best way (using sbt) to organize my build to accommodate the differences, since Scala doesn't have conditional compilation?

Both Luis Miguel and Sascha's answers are correct. Cats does have a good example and SBT has this ability. Couldn't find it in the docs, but it's explained here: https://github.com/twitter/util/issues/219
