Review Comment:
Yes. Because we build `cpp/src/arrow/io_hdfs_internal.cc` unconditionally.
Note that `arrow::hadoop` is a header only target that refers
`cpp/thirdparty/hadoop/include/`.

Review Comment:
Yes.
CMake 3.12 or later is required for object library and target:
https://cmake.org/cmake/help/latest/command/add_library.html#object-libraries
> New in version 3.12: Object libraries can be linked to with
[target_link_libraries()](https://cmake.org/cmake/help/latest/command/target_link_libraries.html#command:target_link_libraries).

Review Comment:
OK. I'll use `ARROW_BOOST_REQUIRED`.

Review Comment:
Yes. The `xsimd` target sets only include path. If we add the `xsimd` target
to link libraries, we can add `-I...` to compiler flags.

Review Comment:
This is just copied from removed `FindBoostAlt.cmake`...
To be honest, I don't know what should be done by this TODO. We may be able
to just remove this TODO.
