Okay so apparently there's an issue with the buildin FindBoost.cmake

The toolchain seems to set some stuff that changed the behaviour of find_path( 
... ) and find_library( ... )

The find_path one can be fixed by passing 
NO_CMAKE_FIND_ROOT_PATH..

basically in the FindBoost.cmake you can replace:
# Look for a standard boost header file.
    find_path(Boost_INCLUDE_DIR
      NAMES         boost/config.hpp
      HINTS         ${_boost_INCLUDE_SEARCH_DIRS}
      PATH_SUFFIXES ${_boost_PATH_SUFFIXES}
      ${_boost_FIND_OPTIONS}
      )
with 
# Look for a standard boost header file.
    find_path(Boost_INCLUDE_DIR
      NAMES         boost/config.hpp
      HINTS         ${_boost_INCLUDE_SEARCH_DIRS}
      PATH_SUFFIXES ${_boost_PATH_SUFFIXES}
      ${_boost_FIND_OPTIONS}
      NO_CMAKE_FIND_ROOT_PATH
      )

That way the include dir gets found again.

However I am still at a loss how to fix the find_library one..

Use find_host_package instead.

actually adding NO_CMAKE_FIND_ROOT_PATH works for getting the boost 
installation. You just have to add /boost in the "find includes" part since the 
old versions have their include files there.
