Are you suggesting I specify the path to each individually? I didn't see a way to do that with the current CLI api. It assumes that the input is only a single path.

Any suggestions for how to proceed? Do I need to add support for split BTF to btf__add_btf() to libbpf? If so, any thoughts on how that should work would be appreciated.
