libbpf v0.8.0 deprecates the bpf_get_link_xdp_id() and
bpf_set_link_xdp_fd() functions. Use meson to detect if
bpf_xdp_attach() is available and if so, use the recommended
replacement functions bpf_xdp_query_id(), bpf_xdp_attach()
and bpf_xdp_detach().

meson is not detecting functions, I am getting following log, any idea
what is going wrong:
Run-time dependency libxdp found: YES 1.2.2
Run-time dependency libbpf found: YES 0.8.1
Has header "linux/if_xdp.h" : YES
Has header "xdp/xsk.h" : YES

Checking for function "bpf_object__next_program" with dependency libbpf: NO

It is OK, this was my environment issue, libbpf.so permission was wrong
although I compile and installed from source, anyway latest log:
