FindOpenSP
----------
.. versionadded:: 3.25
Finds the OpenSP library. OpenSP is an open-source implementation of the SGML
(Standard Generalized Markup Language) parser.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following :ref:`Imported Targets`:
``OpenSP::OpenSP``
Target encapsulating the OpenSP library usage requirements, available only if
the OpenSP is found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``OpenSP_FOUND``
Boolean indicating whether the (requested version of) OpenSP is available.
``OpenSP_VERSION``
The version of found OpenSP.
``OpenSP_VERSION_MAJOR``
The major version of OpenSP.
``OpenSP_VERSION_MINOR``
The minor version of OpenSP.
``OpenSP_VERSION_PATCH``
The patch version of OpenSP.
``OpenSP_INCLUDE_DIRS``
The include directories containing headers needed to use the OpenSP library.
``OpenSP_LIBRARIES``
Libraries required to link against to use OpenSP. These can be passed to the
:command:`target_link_libraries` command when not using the ``OpenSP::OpenSP``
imported target.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``OpenSP_INCLUDE_DIR``
The OpenSP include directory.
``OpenSP_LIBRARY``
The absolute path of the ``osp`` library.
``OpenSP_MULTI_BYTE``
True if ``SP_MULTI_BYTE`` was found to be defined in OpenSP's ``config.h``
header file, which indicates that the OpenSP library was compiled with support
for multi-byte characters. The consuming target needs to define the
``SP_MULTI_BYTE`` preprocessor macro to match this value in order to avoid
issues with character decoding.
Examples
^^^^^^^^
Finding the OpenSP library and linking it to a project target:
.. code-block:: cmake
find_package(OpenSP)
target_link_libraries(project_target PRIVATE OpenSP::OpenSP)
