BC2A-1408: Fix hardcoded path for dynamically generated c file

[cedelavergne-ledger]

The Makefile dynamically creates a c file, and its corresponding obj was hardcoded.

There is no need to declare the obj file, that will be dynamically computed by the SDK.

In addition fix the test workflow, replacing a package version.

The dev already did soemthing in the original repo to improve this : jelurida-dev@8cd928d
I think we should go for the same solution

I'm wondering if this is going to cause a merge issue for #5, but if it is the case, we would be able to revert this Pr and then merge without conflicts...
What do you think about it?

Hey, I'm not sure you're coordinating with Xavier or Victor. We just finished the security audit and changes from develop will probably merge to master soon. I would advise to wait until then to make any other changes.

Hi,

No worries. I will of course wait until you have merged before re-sync my PR and fix remaining points, if any.
