Generate a source or header file that includes:

constexpr const char *gitsha1()
{
    return "b35039fc8937f1327e6498c2963b0eadc88b1200";
}

Personally, for my Git ID scripts, I include the output of git describe, which
will relate to the latest tag found in history and is thus more convenient.

$ git describe --tags
