When make tries to build `objdir/b.obj' the pattern rule after substitution
will look like this (% = `b'):
objdir/b.obj: b.cpp
@echo g++ -o $@ -c $<
Then to test if rule is applicable, make checks if prerequisites (`b.cpp'
in our case) exist or can be made. Obviously there is no `b.cpp' in current
dir (it is in `src1/'). So you need to add `src1' to the list of dirs make
will look for `.cpp' files:
vpath %.cpp $(dir $(SRCS))
-boris
