https://arrow.apache.org/docs/cpp/env_vars.html#envvar-ARROW_USER_SIMD_LEVEL > by default, SSE4.2 optimizations are enabled on x86 builds: therefore, with this default setting, Arrow C++ does not work at all on a CPU without support for SSE4.2. This setting can be changed using the `ARROW_SIMD_LEVEL` CMake variable so as to either raise or lower the optimization level. -- This is an automated message from the Apache Git Service.
