+Principe des applications dans CGoGN_Apps
+
+
+
+Faire un repertoire CGoGN_Apps ou on veut. Y mettre des sous répertoires
+contenant chacun une application/
+
+Le CMakeLists.txt a la racine de l'application doit commencer par
+
+cmake_minimum_required(VERSION 2.8)
+PROJECT(NOM_DE_L_APPLICATION)
+SET(CGoGN_ROOT_DIR ${CMAKE_SOURCE_DIR}/../../CGoGN)
+INCLUDE(${CGoGN_ROOT_DIR}/build/apps_cmake.txt)
+
+Le ../../CGoGN correspond au chemin relatif vers votre version de CGoGN
+(ici placée au même niveau que CGoGN_Apps)
+
+
+Si vous voulez faire des sous répertoires release et debug:
+
+add_subdirectory(${CMAKE_SOURCE_DIR}/Release Release)
+IF (NOT WIN32)
+	add_subdirectory(${CMAKE_SOURCE_DIR}/Debug Debug)
+ENDIF (NOT WIN32)
+
+
+
+Le CMakeLists (Release par exemple) doit ensuite contenir
+
+
+SET(CMAKE_BUILD_TYPE Release)
+
+link_directories( ${CGoGN_ROOT_DIR}/lib/Release/)
+
+include_directories(
+	${CGoGN_ROOT_DIR}/include		# for CGoGN
+	${COMMON_INCLUDES}				# for thirdparty & system
+	${CMAKE_CURRENT_SOURCE_DIR}		# for application
+	${CMAKE_CURRENT_BINARY_DIR}		# for qt (ui,moc,etc.) if necessary
+)
+
+add_executable( mon_exec ${CMAKE_SOURCE_DIR}/mon_source.cpp)
+
+target_link_libraries( mon_exec ${CGoGN_LIBS_R} ${COMMON_LIBS})
+
+
+
+
+Pour le compiler le plus propre est de faire un repertoire build,
+d'aller à l'interieur et de faire ccmake .. (j'ai bien ecrit "..")
+ccmake (ou un equivalent type cmake-gui) permet de mettre à jour les variables,
+ici WITH_QT, WITH_ASSIMP, WITH_NUMERICAL, WITH_ZINRI.
+Ceci ajoutera automatiquement tout ce qu'il faut aux variables COMMON_INCLUDES
+et COMMON_LIBS.
+On peut aussi utiliser cmake avec l'option -D (moins pratique).
