I'd build everything in the 'obj' directories. For example,
cd to obj/subproj1/ and then do
  make -f ../../Makefile subproj1.exe
using vpath to tell the makefile where to find the sources.

vpath can reach back from the object dir to find sources,
but it it can't reach forward from the source dir to say
where to place objects.
