dependency files created during a make are not searched for using VPATH
when used by other target files.

example:

two subdirectories were created.  "obj" for object files and "src" for the
source file.

---------------------------

contents:

src: target.x
obj: 

here's the makefile:
---------------------------
% more tmakefile
VPATH = ../src
target: target.c
target.c: target.x
        cp $(<D)target.x $(<D)$@
---------------------------

here's the execution:
---------------------------
% /usr/local/make -f ../tmakefile -C obj
cp ../src/target.x ../src/target.c
cc     target.c   -o target
cpp: error 0: No source file target.c
make: *** [target] Error 1
---------------------------

the cc command should have been:
cc ../src/target.c -o target

If the makefile runs again, it works (since target.c exists now)
---------------------------
% !!
/usr/local/make -f ../tmakefile -C obj
cc     ../src/target.c   -o target
---------------------------
