# `meson dist` doesn't trigger a build, which is a problem because we
# need to add some configured/built files. The case where we didn't
# build at all is the less annoying (we'd get a failure, which is
# actually acceptable as it warns us). But the case where we would copy
# outdated data is much more insidious (such as wrong INSTALL
# information or wrong git information) as it would be silent.
# See: https://github.com/mesonbuild/meson/issues/10650
# And: https://gitlab.gnome.org/GNOME/gimp/-/issues/7907
# This is why we manually trigger, not only a reconfigure, but also a
# rebuild of the main project before copying data around.

# INSTALL file is generated at configure time.
