-This RFC proposes an easy way to configure build images to allow specifying a `/cnb/config/env.build` CNB environment directory that allows updating the Buildpack `detect` and `build` environment based on the directory.

-The RFC proposes the introduction of the following directory `/cnb/config/env.build` in build images. The directory follows the same convention as a `CNB environment directory`. The notable difference is that the environment variables sourced from this directory are applied **AFTER** processing the user-provided platform environment variables i.e. they should have the highest precedence. These variables should be available during both `detect` and `build` phases (and the `generate` phase in the future).
