Have to build without "warnings as error" using:

% perl tools/builder/build_mfx.pl --cmake=intel64.make.release --no-warn-as-error

Builds fails with:

../../__lib/release/libencode_hw.a(mfx_h264_scd.cpp.o): In function `MfxHwH264Encode::ASC::Get_CpuFeature_AVX2()':
/home/ddd/Work/msdk/_studio/mfx_lib/encode_hw/h264/src/mfx_h264_scd.cpp:582: undefined reference to `__cpu_model'

/home/ddd/Work/msdk/_studio/shared/src/mfx_scd.cpp:12008: undefined reference to `__cpu_model'

Fix is adding -lgcc at end of build line:

4K monitor still not arrived. Sigh. Checked the Amazon tracking, they say they "attempted to deliver". But no delivery slip, and I was there the whole day, and specifically at the announced time (11:58). Grmbl.
