+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.

+
+This code is using the Cryptography API: Next Generation (CNG)
+https://docs.microsoft.com/en-us/windows/desktop/seccng/cng-portal
+
+This API is supported on
+ - Windows Vista or later (client OS)
+ - Windows Server 2008 (server OS)
+ - Windows Embedded Compact 2013 (don't know about Windows Embedded Compact 7)
+
+The code was developed for Windows Embedded Compact 2013 (WEC2013),
+but should be working for all of the above mentioned OSes.
+
+There are 2 restrictions for WEC2013, Windows Vista and Windows Server 2008:
+
+1.) The function "BCryptDeriveKeyPBKDF2" is not available
+
+I found some code which is implementing this function using the deprecated Crypto API here:
+https://www.idrix.fr/Root/content/view/37/54/
+
+I took this code and converted it to the newer CNG API. The original code was more
+flexible, but this is not needed here so i refactored it a bit and just kept what is needed.
+
+The define "HAS_BCRYPTDERIVEKEYPBKDF2" controls whether "BCryptDeriveKeyPBKDF2"
+of the CNG API is used or not. This define must not be set if you are compiling for WEC2013 or Windows Vista.
+
+
+2.) "BCryptCreateHash" can't manage the memory needed for the hash object internally
+
+On Windows 7 or later it is possible to pass NULL for the hash object buffer.
+This is not supported on WEC2013, so we have to handle the memory allocation/deallocation ourselves.
+There is no #ifdef to control that, because this is working for all supported OSes.
