 # Try to find libpcap.

+# To tell this module where to look, a user may set the environment variable
+# PCAP_ROOT to point cmake to the *root* of a directory with include and
+# lib subdirectories for pcap.dll (e.g WpdPack or npcap-sdk).
+# Alternatively, PCAP_ROOT may also be set from cmake command line or GUI
+# (e.g cmake -DPCAP_ROOT=C:\path\to\pcap [...])
