This script checks that all generated file are up-to-date. If some aren't, by
default the scripts reports it and exits in error; with the -u option, it just
updates them instead.
-u Update the files rather than return an error for out-of-date files.
-l List generated files, but do not update them.

# - **/Makefile (to (re)build them with make)
# - **/CMakeLists.txt (to (re)build them with cmake)
