I'm trying with the latest fedora that comes with static libraries,
fedora:32, and there I noticed that we need to look for libzstd as well,
I added it manually to:

target_link_libraries(dwarves ${DWARF_LIBRARIES} ${ZLIB_LIBRARIES} ${LIBBPF_LIBRARIES} ${ARGP_LIBRARY} ${OBSTACK_LIBRARY} ${BZ2_LIBRARY} ${LZMA_LIBRARY} -lzstd)

[root@cc85f3a7b96f dwarves-1.22]# rpm -qa | grep -- -static
zlib-static-1.2.11-21.fc32.x86_64
glibc-static-2.31-6.fc32.x86_64
elfutils-devel-static-0.183-1.fc32.x86_64
xz-static-5.2.5-1.fc32.x86_64
libxcrypt-static-4.4.20-2.fc32.x86_64
libzstd-static-1.4.9-1.fc32.x86_64
elfutils-libelf-devel-static-0.183-1.fc32.x86_64
bzip2-static-1.0.8-2.fc32.x86_64
[root@cc85f3a7b96f dwarves-1.22]# cat /etc/fedora-release
Fedora release 32 (Thirty Two)
[root@cc85f3a7b96f dwarves-1.22]#

now I'm at:

/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/10/../../../../lib64/libdw.a(debuginfod-client.o): in function `__libdwfl_debuginfod_init':

/usr/bin/ld: (.text.startup[.text.startup.group]+0x81): undefined reference to `dlsym'
/usr/bin/ld: (.text.startup[.text.startup.group]+0xe0): undefined reference to `dlclose'

that needs some more magic that I already forgot :-\

But now out to lunch.
