# FindZLIB
# --------
#
# Find the native ZLIB includes and library.
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines :prop_tgt:`IMPORTED` target ``ZLIB::ZLIB``, if
# ZLIB has been found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables:
#
# ::
#
# ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
# ZLIB_LIBRARIES - List of libraries when using zlib.
# ZLIB_FOUND - True if zlib found.
#
# ::
#
# ZLIB_VERSION_STRING - The version of zlib found (x.y.z)
# ZLIB_VERSION_MAJOR - The major version of zlib
# ZLIB_VERSION_MINOR - The minor version of zlib
# ZLIB_VERSION_PATCH - The patch version of zlib
# ZLIB_VERSION_TWEAK - The tweak version of zlib
#
# Backward Compatibility
# ^^^^^^^^^^^^^^^^^^^^^^
#
# The following variable are provided for backward compatibility
#
# ::
#
# ZLIB_MAJOR_VERSION - The major version of zlib
# ZLIB_MINOR_VERSION - The minor version of zlib
# ZLIB_PATCH_VERSION - The patch version of zlib
#
# Hints
