Fermeture du plugin

Tout fonctionne parfaitement, comme tout à l'heure.

Nous pouvons tester si les fichiers .c et .so du plugin ont bien été créé :

ls
autoPlugin.c  autoPlugin.so  CMakeCache.txt  CMakeFiles  cmake_install.cmake  generatednumberlibdynamic  Makefile

Notre plugin a bien été créé et compilé.

Testons avec une autre expression :
