Including an arduino library in Eclipse Neon (undefined reference to) I'm trying for the first time to use Arduino Libraries (Servo.h &amp; Servo.cpp in this case) in Eclipse IDE.

So far I've managed to compile and run Arduino code using this tutorial (I suppose many of you already know it). 

The problem comes when I add the Servo.cpp and Servo.h files and try to run the program:

As you can see in the console output, it compiles correctly, but when it comes to the linker, it doesn't find the function references from the Servo.cpp.

As I have seen in this post, the problem comes from the fact that I need also to generate an .a (static library) file in order to link both .h and .cpp files. Still, I have no idea how I am supposed to generate this file.

For this project, I have just added in arduinoEclipse folder all the .cpp and .h files from C:\arduino\hardware\arduino\avr\cores\arduino, C:\arduino\hardware\arduino\avr\variants\standard &amp; C:\arduino\libraries\Servo. 

Do you see what I could be missing?

Thank you in advance
I don't have eclipse handy right now, so I may not have the menu options verbatim here, but with eclipse there are more steps to including a library than just writing the line in the code.  Go to the project in the project explorer and right click the project name.  Hit import and select the option for importing Arduino libraries into the sketch.  It should bring up a dialog with a list of all the libraries you have installed and you can choose from there.  Then there will be a folder in your project called includes IIRC and it will have a link to the library that you imported.  Now when you compile it will find the library.
