# - Find Parquet (parquet/api/reader.h, libparquet.a, libparquet.so)
#
# This module requires Arrow from which it uses
#  arrow_find_package()
#
# This module defines
#  PARQUET_FOUND, whether Parquet has been found
#  PARQUET_IMPORT_LIB, path to libparquet's import library (Windows only)
#  PARQUET_INCLUDE_DIR, directory containing headers
#  PARQUET_LIBS, deprecated. Use PARQUET_LIB_DIR instead
#  PARQUET_LIB_DIR, directory containing Parquet libraries
#  PARQUET_SHARED_IMP_LIB, deprecated. Use PARQUET_IMPORT_LIB instead
#  PARQUET_SHARED_LIB, path to libparquet's shared library
#  PARQUET_SO_VERSION, shared object version of found Parquet such as "100"
#  PARQUET_STATIC_LIB, path to libparquet.a

# cbodley copied this from the arrow submodule at v6.0.1
# cbodley added the import target Arrow::Parquet to match build_arrow()
