nod-gyp include dirs not working - c++

Question

I met some problem while using node-gyp to build my C++ code. I would like to include some directories that contain *.h file in sub-directory, but it always shows error No such file or directory. Does anyone who have experience with node-gyp can give me some advice.
Here is my directory structure
----libraries
----library
----modules.h // define a_module.h in modules.h
----a_module.h
----a_module.cpp
----src
----main.h
----binding.gyp
----addon.cc
and my binding.gyp file is below:
{
"targets": [
{
"target_name": "addon",
"sources": [
"addon.cc",
"./libraries/src/main.cpp"
],
"include_dirs": [
],
"dependencies": [
"libs"
]
},
{
"target_name": "libs",
"type": "<(library)",
"include_dirs": [
"./libraries/libraru/",
]
}
]
}
I also try the config below:
{
"targets": [
{
"target_name": "addon",
"sources": [
"addon.cc",
"./libraries/src/main.cpp"
],
"include_dirs": [
"./libraries/library/"
]
}
]
}
I try to call my program with the following path: main.cc -> main.h -> modules.h -> a_module.h -> a_module.cpp.
codes in main.cc
#include "./libraries/src/main.h"
codes in main.h
#include "library/modules.h" // <- No such file or directory error occurred
Is there anything wrong in my binding.gyp file?
Thanks for viewing my question.
