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
|
|
^^^^^
|
|
|
|
Set ``OPENSSL_ROOT_DIR`` to the root directory of an OpenSSL installation.
|
|
|
|
.. versionadded:: 3.4
|
|
Set ``OPENSSL_USE_STATIC_LIBS`` to ``TRUE`` to look for static libraries.
|
|
|
|
.. versionadded:: 3.5
|
|
Set ``OPENSSL_MSVC_STATIC_RT`` set ``TRUE`` to choose the MT version of the lib.
