URL: https://github.com/apache/arrow/issues/50222
### Describe the bug, including details regarding any error messages,
version, and platform.
When included into another project via FetchContent_Declare() Apache Arrow
produces error:
`xsimd/xsimd.hpp: No such file or directory`
Investigation showed that xsimd dependency in Apache Arrow is processed
incorrectly. Here is the patch which fixes the error:
