I modified a couple of cpp files in the examples folder. I'm trying to debug one of them, but I don't really know what I am doing (I admit, I am not amazing with c++).

Does anyone know of a nice way to setup debugging in GTSAM? Particularly for debugging example files? Vscode seems like a nice tool for debugging, and I already have Vscode installed. I am preferably looking for a debugger that is easy to setup. I tried debugging using Vscode but I get an error:

I don't get this error when I build and run the example file from the build folder:
