how to enable folly with sse4.2

[ZhaoHaoRu]

I am trying to use folly in my own project. My project uses the sse4.2 compilation option. When linking, an error is reported: undefined reference to folly::f14::detail::F14LinkCheck<(folly: :f14::detail::F14IntrinsicsMode)2>::check(), according to the comments, this error is caused by compilation flags varying across compilation units, because my own project must use sse4.2. How to solve this error by changing folly's compilation option?

I guess you picked out the dependencies for f14, but you didn't find them all. For example, you probably didn't pick out the detail/Sse.cpp and its header.

I directly commented out the relevant checks in folly/container/detail/F14Table.h, and there were no problems when running.
