FindOpenSSL
-----------
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.
