[CMake] newbie: find_package Boost ceases to work when mixed with CLang CMAKE_TOOLCHAIN_FILE (on Ubuntu 64bit Quantal 12.10)

[ahoros]

I must be missing something very, very obvious about default paths - but I
think I tried every possible option...
I have following cmake commands:

    SET(CMAKE_INCLUDE_PATH
${CMAKE_INCLUDE_PATH};/usr/include/;/usr/local/include/;/usr/include/boost/)
    SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH};/usr/lib/;/usr/)
    set(BOOST_INCLUDEDIR /usr/include/)
    set(BOOST_LIBRARYDIR /usr/lib/)

    SET(Boost_DEBUG 1)
    SET(Boost_DETAILED_FAILURE_MSG TRUE)
    SET(Boost_ADDITIONAL_VERSIONS "1.47" "1.47.0" "1.48" "1.48.0" "1.49"
"1.49.0" "1.50" "1.50.0" "1.51" "" "1.51.0")
    SET(Boost_USE_STATIC_LIBS ON)
    SET(Boost_USE_MULTITHREAD ON)
    find_package(Boost REQUIRED COMPONENTS serialization filesystem
date_time system thread)


and it works on standard gcc toolchain:
-- [ /usr/share/cmake-2.8/Modules/FindBoost.cmake:707 ]  
_boost_INCLUDE_SEARCH_DIRS =
/usr/include/boost;C:/boost/include;C:/boost;/boost/include;/boost;/sw/local/include

-- [ /usr/share/cmake-2.8/Modules/FindBoost.cmake:1107 ] Boost_FOUND = TRUE
-- Boost version: 1.50.0



However,  I have prepared toolchain module file for clang:
INCLUDE(CMakeForceCompiler) #Disables checks
SET(CMAKE_SYSTEM_NAME Generic)

CMAKE_FORCE_C_COMPILER( /usr/bin/clang CLang )
CMAKE_FORCE_CXX_COMPILER ( /usr/bin/clang++ CLang )

SET(CMAKE_C_LINK_EXECUTABLE "/usr/bin/llvm-ld <OBJECTS> -o  <TARGET>
<CMAKE_C_LINK_FLAGS> <LINK_FLAGS> <LINK_LIBRARIES>")
SET(CMAKE_CXX_LINK_EXECUTABLE "/usr/bin/llvm-ld <OBJECTS> -o  <TARGET>
<CMAKE_CXX_LINK_FLAGS> <LINK_FLAGS> <LINK_LIBRARIES>")

SET(CMAKE_FIND_ROOT_PATH /usr/bin)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)


which I evoke like this:
cmake -DCMAKE_TOOLCHAIN_FILE=../inter/CMakeClangToolchain.cmake ../soruce


and that what spoils find_package Boost (!!!)

Boost ver 1.50 is installed from Quantal packages in standard locations:
/usr/include/boost
and
/usr/lib


Is there any better way to use clang with cmake on Ubuntu ?
