+Find the OpenSSL encryption library.
+
+This module finds an installed OpenSSL library and determines its version.
+
+.. versionadded:: 3.19
+  When a version is requested, it can be specified as a simple value or as a
+  range. For a detailed description of version range usage and capabilities,
+  refer to the :command:`find_package` command.
+
+.. versionadded:: 3.18
+  Support for OpenSSL 3.0.
+
+Optional COMPONENTS
+^^^^^^^^^^^^^^^^^^^
+
+.. versionadded:: 3.12
+
+This module supports two optional COMPONENTS: ``Crypto`` and ``SSL``.  Both
+components have associated imported targets, as described below.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+.. versionadded:: 3.4
+
+This module defines the following :prop_tgt:`IMPORTED` targets:
+
+``OpenSSL::SSL``
+  The OpenSSL ``ssl`` library, if found.
+``OpenSSL::Crypto``
+  The OpenSSL ``crypto`` library, if found.
+``OpenSSL::applink``
+  .. versionadded:: 3.18
+
+  The OpenSSL ``applink`` components that might be need to be compiled into
+  projects under MSVC. This target is available only if found OpenSSL version
+  is not less than 0.9.8. By linking this target the above OpenSSL targets can
+  be linked even if the project has different MSVC runtime configurations with
+  the above OpenSSL targets. This target has no effect on platforms other than
+  MSVC.
+
+NOTE: Due to how ``INTERFACE_SOURCES`` are consumed by the consuming target,
+unless you certainly know what you are doing, it is always preferred to link
+``OpenSSL::applink`` target as ``PRIVATE`` and to make sure that this target is
+linked at most once for the whole dependency graph of any library or
+executable:
+
+.. code-block:: cmake
+
+   target_link_libraries(myTarget PRIVATE OpenSSL::applink)
+
+Otherwise you would probably encounter unexpected random problems when building
+and linking, as both the ISO C and the ISO C++ standard claims almost nothing
+about what a link process should be.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``OPENSSL_FOUND``
+  System has the OpenSSL library. If no components are requested it only
+  requires the crypto library.
+``OPENSSL_INCLUDE_DIR``
+  The OpenSSL include directory.
+``OPENSSL_CRYPTO_LIBRARY``
+  The OpenSSL crypto library.
+``OPENSSL_CRYPTO_LIBRARIES``
+  The OpenSSL crypto library and its dependencies.
+``OPENSSL_SSL_LIBRARY``
+  The OpenSSL SSL library.
+``OPENSSL_SSL_LIBRARIES``
+  The OpenSSL SSL library and its dependencies.
+``OPENSSL_LIBRARIES``
+  All OpenSSL libraries and their dependencies.
+``OPENSSL_VERSION``
+  This is set to ``$major.$minor.$revision$patch`` (e.g. ``0.9.8s``).
+``OPENSSL_APPLINK_SOURCE``
+  The sources in the target ``OpenSSL::applink`` that is mentioned above. This
+  variable shall always be undefined if found openssl version is less than
+  0.9.8 or if platform is not MSVC.
+
+Hints
+^^^^^
+
+The following variables may be set to control search behavior:
+
+``OPENSSL_ROOT_DIR``
+  Set to the root directory of an OpenSSL installation.
+
+``OPENSSL_USE_STATIC_LIBS``
+  .. versionadded:: 3.4
+
+  Set to ``TRUE`` to look for static libraries.
+
+``OPENSSL_MSVC_STATIC_RT``
+  .. versionadded:: 3.5
+
+  Set to ``TRUE`` to choose the MT version of the lib.
+
+``ENV{PKG_CONFIG_PATH}``
+  On UNIX-like systems, ``pkg-config`` is used to locate the system OpenSSL.
+  Set the ``PKG_CONFIG_PATH`` environment variable to look in alternate
+  locations.  Useful on multi-lib systems.
