FWIW when using boost with CMake projects I use a slightly modified 
FindBoost.cmake module.

After building boost with this batch file

@echo off
ECHO build start

CALL bootstrap.bat

rmdir lib /S /Q
mkdir lib

set BUILD_OPTIONS=--build-dir=c:\boost\boost_build --layout=versioned 
--stagedir=.\lib toolset=msvc-11.0 link=static threading=multi

ren lib\lib x86
ECHO x86 END

ECHO x64 START

ren lib\lib x64
ECHO x64 END

ECHO build done
