# WARNING WARNING this build pollutes the system root WARNING WARNING
# vdeplug4 depends on s2argv-execs and expects that to be installed.
# Since we include that in this build and it is impossible (for me) to
# let cmake know that it is installed in /tmp/package-vdeplug4/ that
# library is installed in the root as well.
# If someone knows how to deal with this, let me know.
