# Once done, the following will be defined:
#
-# NS3_INCLUDE_DIRS - the NS3 include directories
+# NS3_INCLUDE_DIRS - the ns-3 include directories
# NS3_LIBRARY_PATH - path to the libs
-# NS3_LIBRARIES - link these to use NS3 (full path to libs)
+# NS3_LIBRARIES - link these to use ns-3 (full path to libs)
#
# This could be improved in many ways (patches welcome):
-# - No way to specify a minimal version (v3.10 is hardcoded).
# - No proper find_package() integration
-## ADDING A NS3 VERSION.
-# - Add "ns3.${version}-core ns3.${version}-core-debug ns3.${version}-core-optimized" to the NAME line of the find_library below
-# - Add "include/ns3{version}" to the PATH_SUFFIXES line of the find_path below
