Linking Problems on Raspbian

[dbrgn]

When compiling a project relying on pcap-sys (through pcap-async) on Raspbian 10, I get the following linker error:

The Debian package for libpcap0.8-dev doesn't seem to install a pkg-config file. The headers are here:

...
/usr/include/pcap/bluetooth.h
/usr/include/pcap/bpf.h
/usr/include/pcap/can_socketcan.h
/usr/include/pcap/dlt.h
/usr/include/pcap/export-defs.h
/usr/include/pcap/ipnet.h
/usr/include/pcap/namedb.h
/usr/include/pcap/nflog.h
/usr/include/pcap/pcap.h
/usr/include/pcap/sll.h
/usr/include/pcap/usb.h
/usr/include/pcap/vlan.h
/usr/include/pcap-bpf.h
/usr/include/pcap-namedb.h
/usr/include/pcap.h
...

The shared lib is located at /usr/lib/arm-linux-gnueabihf/libpcap.so and /usr/lib/arm-linux-gnueabihf/libpcap.so.0.8 and /usr/lib/arm-linux-gnueabihf/libpcap.so.1.8.1.

Any ideas how to debug and resolve this?
