# FindDbXml.cmake
#
# Looks for DBXML headers and supporting libraries. If none found, the internal copy
# is built and the check is done again
#
# This module defines (if found, or found after build):
#
# DBXML_INCLUDE_DIR - The DBXML headers
# DBXML_LIBRARY - The DBXML library
# DB_CXX_LIBRARY - The BerkeleyDB C++ library
# XQILLA_LIBRARY - The XQilla library
# XERCESC_LIBRARIES - The xerces C++ library (only if INTERNAL_XERCES is set)
