Lets make things simple, something like:

SRCS = $(wildcard *.cpp */*.cpp */*/*.cpp */*/*/*.cpp)

My guess is that you want to replace it with something like:

OBJS = $(patsubst %.cpp, $(BLD)/%.o, $(notdir $(SRCS)))

So you could add all your directories as searchable with vpath, or
write one rule for each of your source directory that describes how to
make an .o file from a .cpp file.

One way to get the vpath right might be:

empty:=
space:= $(empty) $(empty)

vpath %.cpp $(subst $(space),:,$(sort $(dir $(SRCS))))

I haven't tried the above in any Makefile myself, but I think it should
work. If it still has some bug I hope that it at least will give you some
inspiration on how to fix your Makefile.
