makefile error: opening dependency file .d/file_name.Td: No such file or directory - gcc

Question

I am trying to adapt a makefile (that I found here) that automatically generates dependencies. However, when I run make I get the following error message:
t#t-XPS-13-9365:~/pf/test$ make
g++ -MT .o/test_resamplers.o -MD -MP -MF .d/test_resamplers.Td -std=c++11 -g -Wall -Wextra -pedantic -I/usr/local/include/UnitTest++ -I/usr/include/eigen3 -I../include -c -o .o/test_resamplers.o test_resamplers.cpp
test_resamplers.cpp:155:1: fatal error: opening dependency file .d/test_resamplers.Td: No such file or directory
}
^
compilation terminated.
Makefile:66: recipe for target '.o/test_resamplers.o' failed
make: *** [.o/test_resamplers.o] Error 1
Perhaps I am using the wrong DEPFLAGS variable in my makefile. I did switch the compiler from clang++ in the example to g++. Here's my makefile:
# output binary
BIN := run_tests
# source files
SRCS := \
main.cpp test_cf_filters.cpp test_resamplers.cpp test_rv_eval.cpp \
test_rv_samp.cpp test_utils.cpp
# intermediate directory for generated object files
OBJDIR := .o
# intermediate directory for generated dependency files
DEPDIR := .d
# object files, auto generated from source files
OBJS := $(patsubst %,$(OBJDIR)/%.o,$(basename $(SRCS)))
# compilers (at least gcc and clang) don't create the subdirectories automatically
$(shell mkdir -p $(dir $(OBJS)) >/dev/null)
# C++ compiler
CXX := g++
# linker
LD := g++
# C++ flags
CXXFLAGS := -std=c++11

# linker flags
LDFLAGS := "-L../bin" "-L/usr/local/lib"
# flags required for dependency generation; passed to compilers
DEPFLAGS = -MT $# -MD -MP -MF $(DEPDIR)/$*.Td
# libraries

# compile C++ source files
COMPILE.cc = $(CXX) $(DEPFLAGS) $(CXXFLAGS) $(CPPFLAGS) -c -o $#
# link object files to binary
LINK.o = $(LD) $(LDFLAGS) $(LDLIBS) -o $#
# precompile step
PRECOMPILE =
# postcompile step
POSTCOMPILE = mv -f $(DEPDIR)/$*.Td $(DEPDIR)/$*.d
all: $(BIN)
.PHONY: clean
clean:

You create the object directory with this line:
$(shell mkdir -p $(dir $(OBJS)) >/dev/null)
but you don't create the DEPDIR anywhere, so when the compiler tries to create a file there it fails.
You could add this line to make the dependency directory:
$(shell mkdir -p $(DEPDIR))
Or, add it into the previous shell function.
