error: no field or member function named 'addModule' in 'Build.Step.Compile'

Just want to report an incompatible error in `0.12.0-dev`. It works in `0.11.0`. ``` error: no field or member function named 'addModule' in 'Build.Step.Compile' exe.addModule("chameleon", cham_mod); ``` Does anyone know how to "add module" in the latest master branch? 🤔
