1 # Try to find the ns-3 library.
3 # The user can hint a path using the NS3_HINT option.
5 # Once done, the following will be defined:
7 # NS3_INCLUDE_DIRS - the ns-3 include directories
8 # NS3_LIBRARY_PATH - path to the libs
9 # NS3_LIBRARIES - link these to use ns-3 (full path to libs)
11 # This could be improved in many ways (patches welcome):
12 # - No way to specify a minimal version (v3.26 is hardcoded).
13 # - No proper find_package() integration
15 ## ADDING A ns-3 VERSION.
16 # - Add "ns3.${version}-core ns3.${version}-core-debug ns3.${version}-core-optimized" to the NAME line of the find_library below
17 # - Add "include/ns3{version}" to the PATH_SUFFIXES line of the find_path below
