FindZSTD
|
|
-------
|
|
|
|
Finds the ZSTD library.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This will define the following variables:
|
|
|
|
``ZSTD_FOUND``
|
|
True if the system has the ZSTD library.
|
|
``ZSTD_INCLUDE_DIRS``
|
|
Include directories needed to use ZSTD.
|
|
``ZSTD_LIBRARIES``
|
|
Libraries needed to link to ZSTD.
|
|
``ZSTD_VERSION``
|
|
The version of the ZSTD library which was found.
|
|
|
|
Cache Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables may also be set:
|
|
|
|
``ZSTD_INCLUDE_DIR``
|
|
The directory containing ``zstd.h``.
|
|
``ZSTD_LIBRARY``
|
|
The path to the ZSTD library.
