Summary:                    WriteBasicConfigVersionFile produces bad files
without CMAKE_SIZEOF_VOID_P
Description: 
Modules/BasicConfigVersion-*.cmake.in contain the code

# check that the installed version has the same 32/64bit-ness as the one which
is currently searching:
if(NOT "${CMAKE_SIZEOF_VOID_P}" STREQUAL "@CMAKE_SIZEOF_VOID_P@")
  math(EXPR installedBits "@CMAKE_SIZEOF_VOID_P@ * 8")
  set(PACKAGE_VERSION "${PACKAGE_VERSION} (${installedBits}bit)")
  set(PACKAGE_VERSION_UNSUITABLE TRUE)
endif()

When this is configured with an empty CMAKE_SIZEOF_VOID_P the resulting file
breaks.  This breaks find_package calls that load the version file with an
outright error instead of reporting an unsuitable version.
