Specify path to config.xml

[matteodv99tn]

Hi,
I am using this library since I want to control my Z1 robot through ROS2.

I am doing some testing and it appears that there's no way to specify the config path for the arm.
In particular the following line fails if I execute the z1_ctrl executable in a path that is different from /repo_root/build; it seems that the reported line searches the specific path ../config/config.xml to configure the control components.

z1_controller/main.cpp

Line 40 in 8eb6595

CtrlComponents *ctrlComp = new CtrlComponents(argc, argv);

When running the z1_ctrl executable in a path which doesn't allow to reach the ../config/config.xml file, then I receive the error

Failed to open file: No such file or directory
Failed to load file: No root element.
: No such file or directory
Segmentation fault (core dumped)

Is there a way to specify the path to the configuration file prior to the creation of the control component?

I need this possibility, as a ROS2 user could arbitrary execute his code from any folder (as long as the workspace has been sourced).
