-- On FreeBSD the bundled glog Mutex destructor aborts during Python exit when
-- paddle C extensions are loaded (pthread_rwlock_destroy returns EBUSY).
-- The wheel IS built successfully before the abort, so we should not treat
-- signal 6 (SIGABRT) from Python as a build failure.  Add a cmake touch step
-- so ninja sees the output file and does not retry the command.  The touch
-- runs as a separate cmake -E command: if bdist_wheel exits non-zero from a
-- signal but the wheel file exists the build continues; if no wheel was
-- produced the subsequent cmake steps will detect the missing .whl.
--
-- Also add op_map_codegen as a DEPENDS of the .timestamp custom command that
-- copies python/paddle into the build dir. Upstream is missing this
-- dependency, so with a strictly ordered (-j1 / MAKE_JOBS_UNSAFE) build the
-- copy can run before generate_op_map.py writes phi_ops_map.py, leaving a
-- stale copy that then fails "import paddle" with
-- ModuleNotFoundError: No module named 'paddle.incubate.autograd.phi_ops_map'
-- when setup.py generates the paddle.Tensor stub file, aborting bdist_wheel
-- with no wheel produced.
