| FindOpenSSL |
| ----------- |
| |
| Find the OpenSSL encryption library. |
| |
| Optional COMPONENTS |
| ^^^^^^^^^^^^^^^^^^^ |
| |
| This module supports two optional COMPONENTS: ``Crypto`` and ``SSL``. Both |
| components have associated imported targets, as described below. |
| |
| Imported Targets |
| ^^^^^^^^^^^^^^^^ |
| |
| 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. |
| |
| 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_SSL_LIBRARY`` |
| The OpenSSL SSL library. |
| ``OPENSSL_LIBRARIES`` |
| All OpenSSL libraries. |
| ``OPENSSL_VERSION`` |
| This is set to ``$major.$minor.$revision$patch`` (e.g. ``0.9.8s``). |
| |
| Hints |
| ^^^^^ |
| |
| Set ``OPENSSL_ROOT_DIR`` to the root directory of an OpenSSL installation. |
| Set ``OPENSSL_USE_STATIC_LIBS`` to ``TRUE`` to look for static libraries. |
| Set ``OPENSSL_MSVC_STATIC_RT`` set ``TRUE`` to choose the MT version of the lib. |
