 cmake_minimum_required(VERSION 3.10)
-# 1.0.0 replaced the consumer-sized __AKERR_ERROR_NAMES array with private
-# storage. 2.0.0 makes the library thread safe, which is a second ABI break in
-# the same places: akerr_last_ignored became thread-local storage, and
-# ENSURE_ERROR_READY no longer takes the pool reference that akerr_next_error()
-# now takes for it. Consumer code compiled against a 1.x header would
-# double-count every reference. Hence the major bump and the SOVERSION, so a
-# stale installed libakerror.so cannot be silently paired with new headers.
-# 2.0.1 fixes the unhandled-error exit code, which reported success for any
-# status whose low byte was zero. It adds akerr_exit() but breaks nothing: the
-# soname is unchanged and no existing entry point changed shape.
-# 2.0.2 fixes the AKERR_USE_STDLIB=OFF build, which did not compile at all
-# (issue #12): untangles the header's includes, defines the AKERR_RUNTIME_HEADER
-# freestanding contract, retires PATH_MAX in favor of the AKERR_MAX_ERROR_FNAME_LENGTH
-# build option (default unchanged, so this is not an ABI break), and fails the
-# configure instead of the build when AKERR_THREADS would resolve to pthread
-# under AKERR_USE_STDLIB=OFF. ENSURE_ERROR_READY's pool-exhaustion path now
-# calls akerr_exit() instead of exit(1) directly, which changes that exit code
-# from 1 to AKERR_EXIT_STATUS_UNREPRESENTABLE (125) -- a deliberate behavior
-# change, not an ABI break: no soname move, no entry point changed shape.
