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
^^^^^
A user may set ``ZLIB_ROOT`` to a zlib installation root to tell this
module where to look.
