| configure.in: use pkg-config for libpcap detection |
| |
| The detection of libpcap was based in ${prefix}, which doesn't make |
| sense in a cross-compilation context and can cause host leakage into |
| the target build. |
| |
| So instead, let's use pkg-config to detect libpcap, since it is anyway |
| already use in this configure.in to detect libglib. |
