[Cmake] RE: FindXerces.cmake

[Wheeler, Frederick W (Research)]

I've greatly enhanced the FindXerces.cmake file I sent to this list this
morning.  The new version is below.

If there should be a FindXerces.cmake in CMake/Modules, and this could be
it, let me know if there is anything else I can do to it.

# Find the native Xerces includes and library

# XERCES_INCLUDE_DIR - where to find dom/dom.hpp, etc.
# XERCES_LIBRARIES   - List of fully qualified libraries to link against
when using Xerces.
# XERCES_VERSION_1   - Use this Version
# XERCES_VERSION_2   - Use this Version
# XERCES_FOUND       - Do not attempt to use Xerces if "no" or undefined.
