It will default to 64bit if your OS is 64bit.

On linux the CMake build will by default set the LIB_POSTFIX variable
to 64, its not full proof a sign that you have 64 bit though, as this
is a variable you can override.  This is the only sign I've spotted so
far for a 64 bit build though.  Perhaps someone more expert in CMake
will be able to show us more clearly.

Potentially one could add a flag to CMake build just to show whether
its 32 or 64bit build just for information purposes.

Robert.
