# Look for pcap-config.

# I wish this option could be the default, but it is only enabled with --enable-pcapconfig

# The issue is that libpcap is one of those libraries that is nearly impossible to set up
# properly across all platforms. The 'pcap-config' script is shipped with new versions of libpcap,
# and was created to address portability issues. Unfortunately, the script is not updated properly
# outside of the base distribution. Examples: PF_RING requires 'pthreads', 'numa' and 'rt', but
# this is not reflect that in the script. OS X Xcode 10.11 SDK creates its own very broken
# 'pcap-config' script that only occasionally works for dynamic definitions, and definitely
# does not work for static.
#
# The ability to enable this script exists for corner cases where libpcap distributions starts
# using even more libraries than I am currently not aware of. Originally, you only had to worry
# about 'nl', but now we have to be prepared to add 'nl-3', 'nl-genl-3' and 'dbus-1' to make
# libpcap functional. In the future, there may be more.
