Yes, 2.8.12 does not have CPACK_WIX_PATCH_FILE yet:
http://www.cmake.org/cmake/help/v2.8.12/cmake.html#module:CPackWIX

You would need 3.0:
     www.cmake.org/cmake/help/v3.0/module/CPackWIX.html

The WIX generator is still relatively new and hasn't had as much time as 
the other generators to settle yet.
I am still in progress of adding features as requests come in which 
means that many of the more recent additions will require a more current 
CMake version.
