can tell it to try by setting CMAKE_PREFIX_PATH=/usr/lib/x86_64-linux-gnu
before calling CMake.
But the doku says it looks into "<prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE

and when I test it with cmake 2.8.8 and 2.8.5 this simple CMAkeLists.txt,
cmake_minimum_required(VERSION 2.8)
message(STATUS "CMAKE_LIBRARY_ARCHITECTURE: ${CMAKE_LIBRARY_ARCHITECTURE}")
Find_PACKAGE(BZip2 REQUIRED)
finds libbzip2:

Dave is CMAKE_LIBRARY_ARCHITECTURE set on your system?
$ cmake .. --trace 2>&1 | grep x86
gives here:
