Hi,
I’m working on a library that uses a fork of libcbor as a dependency and I have a conflict issue between the cbor_encode_uint and cbor_encode_tag functions in libcbor and TinyCBOR that is included in the framework. Is there a way to tell the linker to ignore the framework library?

It does not append when I use my fork of libcbor directly in the platformio project and call these functions.
I tested several workarounds but none of them is working, except renaming functions in the libcbor library. If someone has a better solution, It would be great!
