SimGrid uses CMake which is a family of tools designed to build, test, and package software. CMake is used to control the software
compilation process using simple platform- and compiler-independent configuration files. CMake generates native
makefiles and workspaces that can be used in the compiler environment of your choice. For more information see
the <a href="http://www.cmake.org/">official CMake web site</a>.

+@section inside_cmake_addsrc How to add source files?
If you want to rename, add, or delete source file(s) in the SimGrid distribution, you have to edit the
$SIMGRID_INSTALL_PATH/tools/cmake/DefinePackages.cmake configuration file. Files are organized in sections, then find
the section you are interested in and modify it. For instance, a new S4U source file will have to be listed in:
-\verbatim
+@verbatim
set(S4U_SRC
src/s4u/s4u_actor.cpp
src/s4u/s4u_as.cpp
src/s4u/s4u_mailbox.cpp
src/s4u/s4u_storage.cpp
)
-\endverbatim
+@endverbatim
If sources file always have to be included into the library, you are all set. However, ther inclusion may depend on
specific compiling options. For instance, if Boost contexts are not available, you don't want to compile the
src/simix/ContextBoost.* files but still add them to the source distribution. This is done by adding those files to the
EXTRA_DIST list, as follows:
-\verbatim
+@verbatim
if (HAVE_BOOST_CONTEXTS)
set(SIMIX_SRC ${SIMIX_SRC} src/simix/ContextBoost.hpp
src/simix/ContextBoost.cpp)
set(EXTRA_DIST ${EXTRA_DIST} src/simix/ContextBoost.hpp
src/simix/ContextBoost.cpp)
endif()
-\endverbatim
+@endverbatim
Once you're done, you must run "make distcheck" to ensure that you did not forget to add any file to the distributed
archives. This ensures that everything was commited correctly, so you have to first commit before running
"make distcheck". If you forgot something, you want to "git commit --amend". But never amend a commit that you already
pushed to public repositories! Do a second commit in that case.

The first rule is that the content of examples/ must be interesting to the users. It is expected that the users will
take one of these examples and start editing it to make it fit their needs. So, it should be self-contained,
- compile and link the source file (which has to be named as the directory
- add the source and tesh files to the distribution.
-\verbatim
+@verbatim
foreach(x app-masterworker app-pingpong app-pmm app-token-ring async-wait async-waitall
async-waitany cloud-capping cloud-masterworker cloud-migration cloud-multicore cloud-simple
cloud-two-tasks dht-chord dht-pastry energy-consumption energy-onoff energy-pstate energy-ptask energy-vm
set(examples_src ${examples_src} ${CMAKE_CURRENT_SOURCE_DIR}/${x}/${x}.c)
set(tesh_files ${tesh_files} ${CMAKE_CURRENT_SOURCE_DIR}/${x}/${x}.tesh)
endforeach()
-\endverbatim
+@endverbatim
Some more complex examples may require more than one source file. If it is the case for your example, you will find
inspiration in the following example
-\verbatim
+@verbatim
add_executable (bittorrent app-bittorrent/bittorrent.c app-bittorrent/messages.c app-bittorrent/peer.c app-bittorrent/tracker.c app-bittorrent/connection.c)
target_link_libraries(bittorrent simgrid)
set_target_properties(bittorrent PROPERTIES RUNTIME_OUTPUT_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/app-bittorrent)
foreach (file bittorrent connection messages peer tracker)
set(examples_src ${examples_src} ${CMAKE_CURRENT_SOURCE_DIR}/app-bittorrent/${file}.c ${CMAKE_CURRENT_SOURCE_DIR}/app-bittorrent/${file}.h)
endforeach()
-\endverbatim
+@endverbatim
If your example require a deployment file (see @ref deployment for details), name it as the source file adding "_d.xml".
Then add the name of your example to this foreach loop.
-\verbatim
+@verbatim
foreach (file app-bittorrent app-chainsend app-masterworker app-pingpong async-wait
async-waitall async-waitany dht-chord dht-kademlia dht-pastry io-remote platform-properties maestro-set
task-priority)
set(xml_files ${xml_files} ${CMAKE_CURRENT_SOURCE_DIR}/${file}/${file}_d.xml)
endforeach()
-\endverbatim
+@endverbatim
If your example includes extra source, text, XML, or tesh files, add them to the existing lists. Finally, register your
-example to the testing infrastructure. See \ref inside_tests_add_integration for more details.

Note that the structure of the CMakeLists.txt file may vary from one directory to another, but there are enough existing
examples to find one that can be adapted to your own example.
