Building Qt-6.5.1 source 'ERROR: x86 intrinsics support missing.'

[dhfhgshdfsgspirtg]

Hi,

I'm trying to build Qt-6.5.1 from source and I'm getting an error I can't get past on the configure step:

ERROR: x86 intrinsics support missing. Check your compiler settings. If this is an
error, report at https://bugreports.qt.io with your compiler ID and version,
and this output:

${TEST_x86intrin_OUTPUT}

I'm on Ubuntu 20.04
g++ version 11.4.0
cmake version 3.16.3
ninja version 1.10.0
