# This is a wrapper to the tools/pika-mkenums perl script which:
|
|
# * sets a few common values;
|
|
# * updates the ${filebase}enums.c directly in the source directory in
|
|
# order for it to be versionned.
|
|
# * Create a no-op stamp-header file to be included by the resulting
|
|
# enums.c. The goal is to make sure that meson will trigger a rebuild
|
|
# of the enums.c generation before compiling, if the enums.h changed.
