libsession-util/utils/static-bundle.sh

#!/bin/bash
#
# Make libsession-util amalgam builds.
#
# Requires at least two arguments:
# - first arg is the build dir
# - second arg is the archive filename ending with .tar.xz or .zip; *or* an empty string.  If given
#   an archive filename then we package up the .a and headers into the archive (inside the build
#   dir); TAG in the archive name will be replaced with the tag or date+commit.  If empty we just build but don't package anything.
# - extra arguments are passed to the cmake invocation.
