# This module defines the following variables:
#
# SZ_FOUND - System has SZ
# SZ_INCLUDE_DIRS - The SZ include directory
# SZ_LIBRARIES - Link these to use SZ
#
# and the following imported targets:
# SZ::SZ - The SZ compression library target
#
# You can also set the following variable to help guide the search:
# SZ_ROOT - The install prefix for SZ containing the
# include and lib folders
# Note: this can be set as a CMake variable or an
# environment variable. If specified as a CMake
# variable, it will override any setting specified
# as an environment variable.
