CMake should automatically look in lib64 on 64 bit machines.
It basically takes the search path for libraries and changes all
lib to lib64, and searches them first.

So, if you have
/usr/lib
/usr/local/lib

CMake will search the following on a 64 bit machine:
/usr/lib64
/usr/lib
/usr/local/lib64
/usr/local/lib

Perhaps it should search all lib64 first, instead of alternating?
Does this sound like what is happening on your machine?
