+# 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()
