GeographicLib from vendor gtsam

This mean that the GeographicLib will not build with "all" target. also it mean it will not build everything in GeographicLib. only when it needed (on navigation tests) and what it needed (the lib itself).
This save from the javascript compilation error that occur otherwise.

These lines imply that GeographicLib is install when it not found the GeographicLib in system. In practice it not activate the install even if it not found the GeographicLib in system.

I want to delete these line, and set the option to be default false. (similar the state it has today).
If you approve, I will create another push for that.
