# TODO: The --unsafe-perm was added because the CI executes this as root during
# tests and building versions. Once we have the then build system this should not
# be necessary anymore.
#
# NOTE 1: What we actually want are grouped targets, but this would require GNU
# make >= 4.3, so we use the common workaround of an intermediate target.
#
# NOTE 2: NPM people have a totally braindead idea about reproducible builds
# which almost all other people consider a bug, so we have to touch our target
# files. Read https://github.com/npm/npm/issues/20439 and be amazed...
#
# NOTE 3: NPM sometimes terminates with a very unhelpful "npm ERR! cb() never
# called!" message, where the underlying reason seems to be quite obscure, see
# https://npm.community/t/crash-npm-err-cb-never-called/858.
