# FindXercesC
# -----------
#
# Find the Apache Xerces-C++ validating XML parser headers and libraries.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# 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

# Written by Roger Leigh <rleigh@codelibre.net>
