Maybe some additional modification is needed, but for now I expect that > most things may go well. if I see right, then the reason for the inclusion of "immintrin.h" is to provide popcount and coutr_zero implementations when built with C++ standard below C++20, see https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/blob/main/src/include/OSL/mask.h#L18 or when not using GCC or clang where the functions are "builtin". So the inclusion is made from a wrong place. I am going to submit a PR to upstream.
