+-# This module defines the following variables:
+-#
+-#   BLOSC2_FOUND        - System has BLOSC2
+-#   BLOSC2_INCLUDE_DIRS - The BLOSC2 include directory
+-#   BLOSC2_LIBRARIES    - Link these to use BLOSC2
+-#   BLOSC2_VERSION      - Version of the BLOSC2 library to support
+-#
+-# and the following imported targets:
+-#   Blosc2::Blosc2 - The core BLOSC2 library
+-#
+-# You can also set the following variable to help guide the search:
+-#   BLOSC2_ROOT - The install prefix for BLOSC2 containing the
+-#                     include and lib folders
+-#                     Note: this can be set as a CMake variable or an
