# FindXercesC
# -----------
#
# Find the Apache Xerces-C++ validating XML parser headers and libraries.
#
# This module reports information about the Xerces installation in
# several variables. General variables::
#
# 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
#
# The following cache variables may also be set::
#
# XercesC_INCLUDE_DIR - the directory containing the Xerces headers
# XercesC_LIBRARY - the Xerces library
