FindZSTD
--------
Find the native ZSTD includes and library.
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``ZSTD::ZSTD``, if
ZSTD has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
::
ZSTD_INCLUDE_DIRS - where to find zstd.h, etc.
ZSTD_LIBRARIES - List of libraries when using zstd.
ZSTD_FOUND - True if zstd found.
::
ZSTD_VERSION_STRING - The version of zstd found (x.y.z)
ZSTD_VERSION_MAJOR - The major version of zstd
ZSTD_VERSION_MINOR - The minor version of zstd
Debug and Release variants are found separately.
