DESCRIPTION
 When run with the 
--cflags option, 
pcap-config writes to the standard output the 
-I compiler flags required to include libpcap's header files. When run with the 
--libs option, 
pcap-config writes to the standard output the 
-L and 
-l linker flags required to link with libpcap, including 
-l flags for libraries required by libpcap. When run with the 
--additional-libs option, 
pcap-config writes to the standard output the 
-L and 
-l flags for libraries required by libpcap, but not the 
-lpcap flag to link with libpcap itself.
By default, it writes flags appropriate for compiling with a dynamically-linked version of libpcap; the --static flag causes it to write flags appropriate for compiling with a statically-linked version of libpcap.
