Findzstd
-------
Finds the Zstandard (zstd) library.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following imported targets, if found:
``zstd::libzstd_shared``
The shared Zstandard library
``zstd::libzstd_static``
The shared Zstandard library
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``zstd_FOUND``
True if the system has the Zstandard library.
``zstd_VERSION``
The version of the Zstandard library which was found.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``zstd_INCLUDE_DIR``
The directory containing ``zstd.h``.
``zstd_STATIC_LIBRARY``
The path to the Zstandard static library.
``zstd_SHARED_LIBRARY``
The path to the Zstandard shared library.
``zstd_DLL``
The path to the Zstandard DLL.
