Build Error : Undefined reference to folly::detail::SimdSplitByCharImplToStrings

Hello,

Trying to build from source using the latest github clone versions (3/20) of folly and wdt and hitting the following :

[ 74%] Linking CXX executable _bin/wdt/wdt

Latest source folly checkout is in ../folly/ and not built

I am meeting the same problem

you need to update the file CMakeList.txt:

   "${FOLLY_SOURCE_DIR}/folly/hash/detail/Crc32cDetail.cpp"
   "${FOLLY_SOURCE_DIR}/folly/hash/detail/Crc32CombineDetail.cpp"
   "${FOLLY_SOURCE_DIR}/folly/ScopeGuard.cpp"
   "${FOLLY_SOURCE_DIR}/folly/detail/SplitStringSimd.cpp"     # <== add this
