# Stamp the build's identity into GameVersion.cpp. Both strings come from the
# caller with -D, and CI passes them: it pins them once, where it decides what the
# release is, so the parallel build jobs cannot stamp identities that disagree.
#
# A build nobody identified is a local build, and says so rather than guessing
# from HEAD. Keeping such a guess honest would mean re-running configure on every
# commit, and it would buy nothing: only what we package is archived with its PDB,
# and a local crash report is symbolized against the PDB next to the exe.
#
# GIT_SHA lands in czVersionString, which is both the savegame compatibility key
# and the crash-report key. It is the bare short SHA and nothing else — a `git
# describe` string cannot serve here, because czVersionString is only 16 bytes and
# describe puts the SHA last, so it is exactly the discriminating part that would
# get clipped off. The budget is 15 chars + NUL: the string is stored in the
# savegame header as SAVED_GAME_HEADER::zGameVersionNumber (GAME_VERSION_LENGTH),
# so its size is a binary format constant and cannot grow. CI passes 9 hex, well
# past what uniqueness needs (git's own auto-abbrev picks 8 for this repo).
# Overshooting it is an error rather than a truncation, because a clipped SHA is
# how two different builds end up claiming to be the same one.
