1 # Cmake macro to search for the SimGrid library.

5 # This file is free software; you can redistribute it and/or modify it
6 # under the terms of the license (GNU LGPL) which comes with this package.
7
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
