+For that, you need <a href="https://github.com/simgrid/simgrid/blob/master/FindSimGrid.cmake">FindSimGrid.cmake</a>,
+that is located at the root of the SimGrid tree. You can either copy
+this file into the `cmake/Modules` directory of your project, or use
+the version installed on the disk. Both solutions present advantages
+and drawback: if you copy the file, you have to keep it in sync
+manually but your project will produce relevant error messages when
+trying to compile on a machine where SimGrid is not installed. Please
+also refer to the file header for more information.
