 #  Since SimGrid header files require C++17, so we set CMAKE_CXX_STANDARD to 17.
 #    Change this variable in your own file if you need a later standard.
 
+# DEVELOPPERS OF MPI PROGRAMS USING SIMGRID
+#   You should use smpi_c_target() on the targets that are intended to run in SMPI.
+#   ${SMPIRUN} is correctly set if it's installed.

+#   Example:
+#     add_executable(roundtrip roundtrip.c)
+#     smpi_c_target(roundtrip)
+#
+#     enable_testing()
+#     add_test(NAME Roundtrip
