FindXercesC
-----------
.. versionadded:: 3.1
Finds the Apache Xerces-C++ validating XML parser headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
This module defines the following :ref:`Imported Targets`:
``XercesC::XercesC``
.. versionadded:: 3.5
Target encapsulating the Xerces-C++ library (``xerces-c``) usage requirements,
available only if Xerces-C++ is found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``XercesC_FOUND``
Boolean indicating whether the Xerces-C++ is found.
``XercesC_VERSION``
The version of the found Xerces-C++ library.
``XercesC_INCLUDE_DIRS``
Include directories needed to use Xerces-C++.
``XercesC_LIBRARIES``
Libraries needed to link for using Xerces-C++.
``XercesC_LIBRARY``
The path to the Xerces-C++ library (``xerces-c``), either release or debug
variant.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``XercesC_INCLUDE_DIR``
The directory containing the Xerces-C++ headers.
``XercesC_LIBRARY_RELEASE``
.. versionadded:: 3.4
The path to a release (optimized) variant of the Xerces-C++ library.
``XercesC_LIBRARY_DEBUG``
.. versionadded:: 3.4
The path to a debug variant of the Xerces-C++ library.
Examples
^^^^^^^^
Finding the Xerces-C++ library and linking it to a project target:
.. code-block:: cmake
find_package(XercesC)
target_link_libraries(project_target PRIVATE XercesC::XercesC)
