getting cmake errors

Hello all !

I just spend a full day trying to get boost-cmake working 
without success.

I tried two options as described here:
http://sodium.resophonic.com/boost-cmake/current-docs/exported_targets.html

I did a test project that looks like:

-------------------------------------------------
cmake_test
-- boost
       -- CMakeLists.txt
       --
       -- other boost directories ...
-- build (output of cmake)
-- main.cpp
-- CMakeLists.txt
-------------------------------------------------

CMakeLists.txt contains:
-------------------------------------------------
cmake_minimum_required(VERSION 2.6.4)

include_directories(boost)
#
#  Note "EXCLUDE_FROM_ALL" means don't build anything from 
this
#  subdirectory by default; only if specifically
