Using Xerces version with CMake

I've been googling for a smarter FindXerces cmake module, that would take into account the version of Xerces-C library, but I couldn't find anything. I guess there might be better ways to do it but here is my solution. If you know a better way I'm open to suggestions.

FindXercesC.cmake

# - Try to find Xerces-C
# Once done this will define
#
#  XERCESC_FOUND - system has Xerces-C
#  XERCESC_INCLUDE - the Xerces-C include directory
#  XERCESC_LIBRARY - Link these to use Xerces-C
#  XERCESC_VERSION - Xerces-C found version

IF (XERCESC_INCLUDE AND XERCESC_LIBRARY)
# in cache already
SET(XERCESC_FIND_QUIETLY TRUE)
ENDIF (XERCESC_INCLUDE AND XERCESC_LIBRARY)

FIND_PATH(
XERCESC_INCLUDE
NAMES xercesc/util/XercesVersion.hpp
PATHS c:/Libs/xerces-c_2_8_0 ${XERCES_INCLUDE_DIR}
PATH_SUFFIXES xercesc)

FIND_LIBRARY(
 XERCESC_LIBRARY
 NAMES xerces-c xerces-c_2
 PATHS ${XERCES_LIBRARY_DIR})

IF (XERCESC_INCLUDE AND XERCESC_LIBRARY)
SET(XERCESC_FOUND TRUE)
ELSE (XERCESC_INCLUDE AND XERCESC_LIBRARY)
SET(XERCESC_FOUND FALSE)
ENDIF (XERCESC_INCLUDE AND XERCESC_LIBRARY)

IF(XERCESC_FOUND)

FIND_PATH(XVERHPPPATH NAMES XercesVersion.hpp PATHS
 ${XERCESC_INCLUDE}/xercesc/util  NO_DEFAULT_PATH)

IF ( ${XVERHPPPATH} STREQUAL XVERHPPPATH-NOTFOUND )
 SET(XERCES_VERSION "0")
ELSE( ${XVERHPPPATH} STREQUAL XVERHPPPATH-NOTFOUND )
 FILE(READ ${XVERHPPPATH}/XercesVersion.hpp XVERHPP)

 STRING(REGEX MATCHALL "\n *#define XERCES_VERSION_MAJOR +[0-9]+" XVERMAJ
   ${XVERHPP})
 STRING(REGEX MATCH "\n *#define XERCES_VERSION_MINOR +[0-9]+" XVERMIN
   ${XVERHPP})
 STRING(REGEX MATCH "\n *#define XERCES_VERSION_REVISION +[0-9]+" XVERREV
   ${XVERHPP})

 STRING(REGEX REPLACE "\n *#define XERCES_VERSION_MAJOR +" ""
   XVERMAJ ${XVERMAJ})
 STRING(REGEX REPLACE "\n *#define XERCES_VERSION_MINOR +" ""
   XVERMIN ${XVERMIN})
 STRING(REGEX REPLACE "\n *#define XERCES_VERSION_REVISION +" ""
   XVERREV ${XVERREV})

 SET(XERCESC_VERSION ${XVERMAJ}.${XVERMIN}.${XVERREV})

ENDIF ( ${XVERHPPPATH} STREQUAL XVERHPPPATH-NOTFOUND )

IF(NOT XERCESC_FIND_QUIETLY)
 MESSAGE(STATUS "Found Xerces-C: ${XERCESC_LIBRARY}")
 MESSAGE(STATUS "              : ${XERCESC_INCLUDE}")
 MESSAGE(STATUS "       Version: ${XERCESC_VERSION}")
ENDIF(NOT XERCESC_FIND_QUIETLY)
ELSE(XERCESC_FOUND)
MESSAGE(FATAL_ERROR "Could not find Xerces-C !")
ENDIF(XERCESC_FOUND)

MARK_AS_ADVANCED(XERCESC_INCLUDE XERCESC_LIBRARY)

Than you can use it like this:
CMakeLists.txt

#
# Xerces-C
#
INCLUDE(${CMAKE_MODULE_PATH}/FindXercesC.cmake)

IF (XERCESC_FOUND)
 # using COMPARE_VERSION_STRINGS instead of COMPARE_VERSION for staying compatible with cmake 2.4
 COMPARE_VERSION_STRINGS("${XERCESC_VERSION}" 2.8.0 result)

 IF (result LESS 0)
   MESSAGE(FATAL_ERROR "Xerces ${XERCESC_VERSION} not supported.
 Only 2.8.0, 3.0.1 and newer versions are supported")
 ELSE (result LESS 0)
   MESSAGE(STATUS "Found Xerces ${XERCESC_VERSION} -- ${XERCESC_LIBRARY}")
   INCLUDE_DIRECTORIES(${XERCESC_INCLUDE})
   SET(requiredlibs ${requiredlibs} ${XERCESC_LIBRARY})
 ENDIF (result LESS 0)

ENDIF (XERCESC_FOUND)
