库包含未检测到包含路径中的标头

我正在尝试使用mbed库设置一个makefile项目，以便在以后要使用的更大项目中使用。我已经像这样设置了项目目录...

具体来说，我的错误是在lib/mbed/platform.h，它尝试包含device.h。我有一个应该将其添加到包含路径的makefile，但是g ++似乎仍然找不到它。这是确切的错误...

arm-none-eabi-g++    -c -o main.o source/main.cc

main.cc的第1行是 #include "../lib/mbed/mbed.h"

NUCLEO_F446RE.mk定义了我正在使用的特定于设备的包含路径，我希望能够.mk基于传递给makefile的变量来选择要使用的文件，以便我可以轻松地使用其他mbed板。这是NUCLEO_F446RE.mk...的内容

好吧，这是我的makefile。我一直在努力使一切保持整洁。

将简单的项目导出到makefile之后，我在这里拥有的许多代码都是基于联机mbed IDE的输出。但是，导出将所有内容都放在一个目录中，当我开始做更大的项目并可能添加更多的库时，这将非常混乱。奇怪的是，当我使用单目录导出的版本时，该项目的编译没有任何错误。这里发生了什么？为什么 在多目录版本中看不到g ++ device.h ？

编辑2016-05-09：对Makefile进行细微调整，出现同样的错误。
