+AVRO
+--------
+
+Find the native AVRO includes and library.
+Heavily inspired by the official FindZLIB cmake module v3.27.
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+This module defines :prop_tgt:`IMPORTED` target ``AVRO::AVRO``, if
+AVRO has been found.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+::
+
+  AVRO_INCLUDE_DIRS   - where to find zip.h, unzip.h, etc.
+  AVRO_LIBRARIES      - List of libraries when using avro.
+  AVRO_FOUND          - True if avro found.
+
+Hints
+^^^^^
+
+A user may set ``AVRO_ROOT`` to a avro installation root to tell this
+module where to look.
