How do I specify that CMake should use a different link_directories value depending on whether the target is 32-bit or 64-bit? For example, 32-bit binaries need to link with 32-bit Boost, 64-bit binaries need to link with 64-bit Boost.

    You do something along these lines

      if( CMAKE_SIZEOF_VOID_P EQUAL 8 )
    set( BOOST_LIBRARY "/boost/win64/lib" )
  else( CMAKE_SIZEOF_VOID_P EQUAL 8 )
    set( BOOST_LIBRARY "/boost/win32/lib" )
  endif( CMAKE_SIZEOF_VOID_P EQUAL 8 )
  set( CMAKE_EXE_LINKER_FLAGS ${BOOST_LIBRARY} )
