Configuring Snort (github clone) with autotools does not recognize building option with --enable-large-pcap. Building with cmake on the other hand allows --enable-large-pcap.

$ sudo ./configure --prefix=/usr/local/s3 --enable-ppm --enable-perf-profiling --enable-debug --enable-debug-msgs --enable-shell --enable-gdb --enable-large-pcap --enable-linux-smp-stats --with-pcap-includes=/usr/local/include --with-pcap-libraries=/usr/local/lib
config.status: executing depfiles commands
config.status: executing libtool commands
configure: WARNING: unrecognized options: --enable-large-pcap

$ sudo ./configure_cmake.sh --prefix=/usr/local/s3 --enable-ppm --enable-perf-profiling --enable-debug --enable-debug-msgs --enable-shell --enable-gdb --enable-large-pcap --enable-linux-smp-stats --with-pcap-includes=/usr/local/include --with-pcap-libraries=/usr/local/lib
-- Configuring done
-- Generating done
-- Build files have been written to: /usr/src/setup/snort3/build

Looking at ./configure --help vs. ./configure_cmake.sh --help shows that --enable-large-pcap option is listed in the configure_cmake help, but not listed in configure help.
