I have solved the problem. The following works:

lib wrappers
   : #sources
     ../../models/aorder.cls
     ../../models/deed.cls
     ../../models/discrete.cls
   : # requirements
     <link>static
   ;
cpp-pch stdafx_pch
   : # sources
     stdafx.h
   : # requirements
     <source>stdafx.cpp
     <implicit-dependency>wrappers
   ;
