This module provides the following Imported Targets:

ZLIB::ZLIB: Added in version 3.1.

Target that encapsulates the zlib usage requirements. It is available only when zlib is found.

This module defines the following variables:

The version of zlib found.
ZLIB_INCLUDE_DIRS: Include directories containing zlib.h and other headers needed to use zlib.
ZLIB_LIBRARIES: List of libraries needed to link to zlib.

Changed in version 3.4: Debug and Release library variants can be now found separately.

This module accepts the following variables:

ZLIB_ROOT: A user may set this variable to a zlib installation root to help locate zlib in custom installation paths.
ZLIB_USE_STATIC_LIBS: Added in version 3.24.

Set this variable to ON before calling find_package(ZLIB) to look for static libraries. Default is OFF.
