For those of you who use that kind of stuff, I made a docker container with the proper packages installed for clang and JUCE dependencies. I’ll probably add some versioning in the future to be able to have a defined environment for a given tag.

It doesn’t contain any SDK though (nor JUCE), since it is hosted on a public hub.
