Very compact and nice. But trying it, it wont work.
For 'bin/animation.exe', it expands to:
 bin/animation.exe: $(LIBS)
   link -nologo -debug -incremental:no -map -subsystem:windows
     -out:bin/controls.exe lib/Qwt.lib ...

All the .obj files are missing!?
Trying a:
  .SECONDEXPANSION: $(animation_OBJ)

does not make a difference.

Also a 'make -p' show:
  bin/animation.exe: lib/Qwt.lib
and nothing else.

Qwt.lib is part of $(LIBS).
