Prerequisites

• I am running the latest code. Mention the version if possible as well.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new and useful enhancement to share.

Feature Description

In order to speedup repeated builds, add ccache to the Dockerfiles.

Please note: I am not familiar with the project's build environment/needs.

Motivation

speedup repeated builds

Possible Implementation

An approach could involve the following changes in the builder-stage:

• install ccache
• use a mount in the build step for caching like:

RUN --mount=type=cache,target=/root/.cache/ccache ...

add ccache directory to .gitignore
