* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon. * For macOS sse2neon.h is included as part of the precompiled libraries. * For Linux it is enabled if the sse2neon.h header file is detected. However this library does not have official releases and is not shipped with any Linux distribution, so manual installation and configuration is required to get this working. Ref D8237, T78710
