"make uninstall" not up-to-date
The "make uninstall" target is not up-to-date.
For example, it lists obsolete include directories (include/simix, include/msg, ...). More recent files are not removed (e.g. the python library).
The following Cmake FAQ entry may help: https://gitlab.kitware.com/cmake/community/-/wikis/FAQ#can-i-do-make-uninstall-with-cmake
If it's decided to fix and keep this target, maybe a check has to be added to "make distcheck".
