   8 # The user can hint a path using the SimGrid_PATH option.
   9 #
  10 # Once done, the following will be defined:
  11 #
  12 #  SimGrid_INCLUDE_DIR - the SimGrid include directories
  13 #  SimGrid_LIBRARY - link your simulator against it to use SimGrid
  14 #
  15 # Afterward, you should probably do the following:
  16 #
  17 #  include_directories("${SimGrid_INCLUDE_DIR}" SYSTEM)
  18 #  target_link_libraries(your-simulator ${SimGrid_LIBRARY})
  19 #
  20 # This could be improved in many ways (patches welcome):
  21 #  - Not finding SimGrid is fatal. But who would want to
  22 #    overcome such a desperate situation anyway? ;)
  23 #  - No way to specify a minimal version
  24 #  - No proper find_package() integration
