Embedding application build time/date (maybe git hash)

[cmorgan]

Hello.

I'm looking to embed the application build time/date into my binary and maybe the git hash. Any recommendations for how to properly integrate that kind of thing into the build process? I've reviewed http://esp-idf.readthedocs.io/en/v2.1/a ... d%20system but still not sure which is the best approach to take to embed that information.

Maybe similar to how IDF_VER is done

Take a look at https://github.com/stoggi/cmake-git-version.

It works in a similar way to the IDF_VER that WiFive mentioned but with a bit of Python wrapping it for extra checking.
