# Slackware build script for helm

# Written by Zbigniew Baniewski, <Zbigniew [dot] Baniewski [at] gmail [dot] com>

# 20230630 bkw: Modified by SlackBuilds.org, BUILD=2:
# - install plugins to /usr/lib64/lv2 on 64-bit.
# - stop writing to /root/.helm during the build.
# - install lv2 shared lib +x.
# - add gtk-update-icon-cache to doinst.sh.

# 20220323 bkw: Modified by SlackBuilds.org: fix 32-bit build.

# TODO: since this uses jack, it needs the setcap stuff.
