I am trying to set up a makefile project using the mbed library for use in a larger project I am wanting to do later on. I have the project directory set up like this...
.
|-- Doxyfile
|-- NUCLEO_F446RE.mk
|-- Nucleo_blink.map
|-- asm
|-- attach.gdb
|-- debug
|-- gdb-pipe.cfg

`-- src
`-- main.cc
Specifically, my error is in lib/mbed/platform.h, which tries to include device.h. I have a makefile that should add it to the include path, but g++ still seems to be unable to find it. Here is the exact error...
arm-none-eabi-g++ -c -o main.o source/main.cc
In file included from source/../lib/mbed/mbed.h:21:0,
from source/main.cc:1:
source/../lib/mbed/platform.h:21:20: fatal error: device.h: No such file or directory
#include "device.h"
^
compilation terminated.
<builtin>: recipe for target 'main.o' failed
make: *** [main.o] Error 1
Line 1 of main.cc is #include "../lib/mbed/mbed.h"
NUCLEO_F446RE.mk defines the device-specific include path I am using, and I hope to be able to be able to choose the .mk file to use based on a variable I pass to the makefile, so that I can easily use a different mbed board if I want. Here are the contents of NUCLEO_F446RE.mk...

For good measure, here is my makefile. I have been trying to keep everything as neat as possible.

A lot of the code I have here is based on the output from the online mbed IDE after exporting a simple project to a makefile. However, the export had everything in a single directory, and that will be extremely messy as I start doing larger projects and possibly add more libraries. The strange part is that this project compiles without any errors when I use the single-directory exported version. What is going on here? Why is g++ not seeing device.h in my multi-directory version?
EDITS 2016-05-09: Minor tweaks to makefile, same error.
