With GNAT/GNAT Project, there's package Naming: roughly,

   package Naming is
     case Option is
       when "simple" =>
          for Body ("Pack.Child") use "pack-child-simple.adb";
       when "complex" =>
          for Body ("Pack.Child") use "pack-child-complex.adb";
     end case;
   end Naming;
