> Parquet is an optional dependency of the dataset layer, but it appears that {{FindArrowDataset.cmake}} requires Parquet unconditionally.
> Example:
> https://app.travis-ci.com/github/apache/arrow/jobs/548648734#L3513
> {code}
>   Could NOT find Parquet (missing: PARQUET_INCLUDE_DIR PARQUET_LIB_DIR
>   PARQUET_SO_VERSION)
> Call Stack (most recent call first):
>   /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE)
>   cmake_modules/FindParquet.cmake:115 (find_package_handle_standard_args)
>   cmake_modules/FindArrowDataset.cmake:47 (find_package)
>   CMakeLists.txt:432 (find_package)
