Thanks, I changed to:

macro(ADD_SUBDIRECTORIES)
  set(prefix " + ")
  MESSAGE(STATUS "add_subdirectories: ${ARGN}")
  foreach(subdir ${ARGN})
    MESSAGE(STATUS "${prefix}${subdir}")
    add_subdirectory(${subdir})
  endforeach(subdir ${ARGN})
endmacro(ADD_SUBDIRECTORIES)

and got:

-- Scanning for sub projects in extra:
-- Adding est;boost;threadpool
-- add_subdirectories: est;boost;threadpool
--  + est
--  + boost
-- Scanning ...

The last is missing, why?

Thanks,
