"ERROR: To build outside a git work tree, you must explicitly
set the version, either by writing it to a file gpb.vsn,
or by creating a versioned archive, and then unpack and
build that.
If you want to create a versioned archive, then
use helpers/mk-versioned-archive.
The helpers/mk-versioned-archive can be used from a git worktree
or from eg Github's automatically generated tar/zip files
or similar. If you use it from a (non-shallow) git work tree
with tags intact, the version will get picked up automatically,
otherwise you must know the proper version and specify it manually,
see mk-versioned-archive --help for further assistance.
For further info, see the README.md, the section section
named Building outside of a git work tree.").
