libbpf-0.5.0 is present, since CMakeLists.txt checked for >= 0.4.0.
My fault, knowing the flux that libbpf is in getting to 1.0 I should
have retested with the perf tools container based tests.
Can you think about some fix for that? Lemme see if BTF_KIND_DECL_TAG is
a define or an enum...
Just bumping this line
pkg_check_modules(LIBBPF REQUIRED libbpf>=0.4.0)
to the right version would absolutely be sufficient for us. Of course, that
requires that the libbpf project itself at least manages to make tags
regularly.
Change above version 0.4.0 to 0.6.0 should work as libbpf 0.6.0 contains
all the changes related to BTF_KIND_{TYPE,DECL}_TAGs.
