-# Once done, the following will be defined:

-# CMake >= 2.8.12:
-# Target SimGrid::Simgrid
+# USERS OF PROGRAMS USING SIMGRID
+# -------------------------------
#
-# Use as:
-# target_link_libraries(your-simulator SimGrid::SimGrid)
+# If cmake does not find this file, add its path to CMAKE_PREFIX_PATH:
+# CMAKE_PREFIX_PATH="/path/to/FindSimGrid.cmake:$CMAKE_PREFIX_PATH" cmake .
+#
+# If this file does not find SimGrid, define SimGrid_PATH:
+# SimGrid_PATH=/path/to/simgrid cmake .

+#
+# DEVELOPERS OF PROGRAMS USING SIMGRID
+# ------------------------------------
#
-# Older CMake (< 2.8.12)
-# SimGrid_INCLUDE_DIR - the SimGrid include directories
-# SimGrid_LIBRARY - link your simulator against it to use SimGrid
+# 1. Include this file in your own CMakeLists.txt
+# Either by copying it in your tree, or (recommended) by using the
+# version automatically installed by SimGrid.
+#
+# 2. Afterward, if you have CMake >= 2.8.12, this will define a
+# target called 'SimGrid::Simgrid'. Use it as:
+# target_link_libraries(your-simulator SimGrid::SimGrid)
#
+# With older CMake (< 2.8.12), it simply defines several variables:
+# SimGrid_INCLUDE_DIR - the SimGrid include directories
+# SimGrid_LIBRARY - link your simulator against it to use SimGrid
# Use as:
# include_directories("${SimGrid_INCLUDE_DIR}" SYSTEM)
# target_link_libraries(your-simulator ${SimGrid_LIBRARY})
#
-# This could be improved:
+# In both cases, it also define a SimGrid_VERSION macro, that you
+# can use to deal with API evolutions as follows:
+#
+# #if SimGrid_VERSION < 31800
+# (code to use if the installed version is lower than v3.18)
+# #elif SimGrid_VERSION < 31900
+# (code to use if we are using SimGrid v3.18.x)
+# #else
+# (code to use with SimGrid v3.19+)
+# #endif
+
