Description
I'm not sure if this should be supported or not. But it may be better if Qt build system catches this issue gracefully, so I'm reporting it here.
I get an undefined symbol error when AVX2 is disabled in core, but enabled in Qt3D:

It seems this is related to the following cmake flags:
-DFEATURE_avx2=OFF -DFEATURE_qt3d_simd_avx2=ON
The build was performed with ClangCl (also called clang-cl) on MSVC using Microsoft VS2019 v16.11.10 (current latest) with the upstream LLVM ClangCl 13.0.1. I know that ClangCl is not supported but I think the issue may not be related specifically to ClangCl
