You could handle version detection manually. Something like this should do:

set(RAPTOR_VERSION_IS_OK TRUE)
if(Raptor_FIND_VERSION)
  if(Raptor_FIND_VERSION_EXACT AND
      NOT ${RAPTOR_VERSION} VERSION_EQUAL ${Raptor_FIND_VERSION})
    set(RAPTOR_VERSION_IS_OK FALSE)
  elseif(${RAPTOR_VERSION} VERSION_LESS ${Raptor_FIND_VERSION})
    set(RAPTOR_VERSION_IS_OK FALSE)
  endif()
endif()

And then use RAPTOR_VERSION_IS_OK in the
find_package_handle_standard_args() call.
