FindXercesC
-----------
.. versionadded:: 3.1
Find the Apache Xerces-C++ validating XML parser headers and libraries.
Imported targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.5
This module defines the following :prop_tgt:`IMPORTED` targets:
``XercesC::XercesC``
The Xerces-C++ ``xerces-c`` library, if found.
Result variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``XercesC_FOUND``
true if the Xerces headers and libraries were found
``XercesC_VERSION``
Xerces release version
``XercesC_INCLUDE_DIRS``
the directory containing the Xerces headers
``XercesC_LIBRARIES``
Xerces libraries to be linked
Cache variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``XercesC_INCLUDE_DIR``
the directory containing the Xerces headers
``XercesC_LIBRARY``
the Xerces library
.. versionadded:: 3.4
Debug and Release variants are found separately.
