My code builds fine in the MPLAB X IDE (v5.454), but for usability I want to use VS Code with the MPLAB extensions.

My requirements include the use of the xc32 compiler v2.40. The example video does not cover the use of a specific compiler.
I have that compiler installed, the path is C:/Program Files/Microchip/xc32/v2.40/bin/, but the VS Code IDE cannot find it.
I couldn’t find documentation on how to add it.

I learned in this stackoverflow reply, that I need to add the info into the task.json.

I am confused on how to add the content of all the nested Makefiles into a tasks.json.

Furthermore, I realized that the nested Makefiles are ignored by VS Code and the MPLAB plugins all together.

It is too much to manually add everything

How should I proceed?

Please find below the compilation output from the MPLAB X IDE.

It seems that the numbers in the build/default/production/_ext/<number order a>/<object file a>.o change with every build.

I am new to how to configure such a complex project compilation and do bring a limited computer science background.
