# - Try to find libpcap include dirs and libraries
|
||
|
|
#
|
||
|
|
# Usage of this module as follows:
|
||
|
|
#
|
||
|
|
# find_package(PCAP)
|
||
|
|
#
|
||
|
|
# Variables used by this module, they can change the default behaviour and need
|
||
|
|
# to be set before calling find_package:
|
||
|
|
#
|
||
|
|
# PCAP_ROOT_DIR Set this variable to the root installation of
|
||
|
|
# libpcap if the module has problems finding the
|
||
|
|
# proper installation path.
|
||
|
|
#
|

# Variables defined by this module:
|
||
|
|
#
|
||
|
|
# PCAP_FOUND System has libpcap, include and library dirs found
|
||
|
|
# PCAP_INCLUDE_DIR The libpcap include directories.
|
||
|
|
# PCAP_LIBRARY The libpcap library (possibly includes a thread
|
||
|
|
# library e.g. required by pf_ring's libpcap)
|
||
|
|
# HAVE_PF_RING If a found version of libpcap supports PF_RING
