Sorry, I completely missed one additional change in my directions.

Make the following change as well:

INCLUDE(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake)

==>

INCLUDE(FindPackageHandleStandardArgs)

Note, the second form must have ".cmake" dropped as indicated.

The first form looks only in cmake/modules for
FindPackageHandleStandardArgs.cmake, and since it is not there you got
the above error message.  The second form looks in cmake/modules
first, but if not there looks in the system location for
FindPackageHandleStandardArgs.cmake (which is what we want in this
case).

Hope that additional change allows our build system to find lua5.2,
but if not, I would be happy to help some more.
