Can I install a library outside the library folder in Arduino? - c++

Question

I am working on an Arduino project with a friend and we need 2 external libraries, OneWire and DallasTemperature. I can easily install them on my computer and it will work completely fine, but I actually want to install them in my git folder, so anyone can instantly use my code. My folder structure is as follows:
project_folder/
> libraries/
> OneWire/
> OneWire.h and OneWire.cpp and so
> DallasTemperature/
> DallasTemperature.h and DallasTemperature.cpp and so
> project.ino
In the header files I had to change some references, mostly file paths, so #include <OneWire.h> became #include "../OneWire/OneWire.h" and so and and I got no errors there. In my project.ino I loaded both libraries using #include "libraries/OneWire/OneWire.h" and #include "libraries/DallasTemperature/DallasTemperature.h", which all seem to work, but when I verify my code I get the following error:
C:\Users\<my username>\AppData\Local\Temp\ccZFsuFb.ltrans0.ltrans.o: In function `global constructors keyed to 65535_0_project.ino.cpp.o.1999':

Is there a possibility to install these libraries in my project folder or do I really have to install them seperately on each system?

The answer is of course yes, First you need an IDE can make relative including
you can update your Arduino IDE for version >= 1.6.10 and restructure your folder to be as following
|project_folder/
|>src/
| |> OneWire/
| | > OneWire.h and OneWire.cpp and so
| |> DallasTemperature/
| | > DallasTemperature.h and DallasTemperature.cpp and so
|> project.ino
and then include them from your sketch, like this
#include "src/OneWire/OneWire.h"
#include "src/DallasTemperature/DallasTemperature.h"
Recommend option
use any other IDEs rather than Arduino IDE ... personally I prefer Atmel studio you can download atmel studio for free from the official site
and this lesson show how to convert Arduino sketches to work with atmel studio
