Here is a `CMakeLists.txt` that you can use as a starting point for
your project. It builds two simulators from a given set of source files.
+You first need to copy the `FindSimGrid.cmake` (at the root of the
+SimGrid tree) into the `cmake/Modules` directory of your project.
+
@verbatim
project(MyFirstScheduler)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
+set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
+find_package(SimGrid REQUIRED)
+include_directories(${SimGrid_INCLUDE_DIR})
+
set(SIMULATOR_SOURCES main.c other.c util.c)
add_executable(my_simulator ${SIMULATOR_SOURCES})
-target_link_libraries(my_simulator simgrid)
+target_link_libraries(my_simulator ${SimGrid_LIBRARY})
set(OTHER_SOURCES blah.c bar.c foo.h)
add_executable(other_xp ${OTHER_SOURCES})
-target_link_libraries(other_xp simgrid)
+target_link_libraries(other_xp ${SimGrid_LIBRARY})

Under Linux, you can find which version was used with the following
command that will display the full path to every used dynamic library.
