# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         domoticz
# Descr:       home automation system
# URL:         https://www.domoticz.com/
# Build needs: (Slackware 14.2: cmake > 3.16, gcc > 7)
# Needs:       cereal, jsoncpp, lua53
# Changelog:   
# 2021.1-1:    10/nov/2021 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 
# Run 'sh domoticz.SlackBuild' to build a Slackware package.
# The package (.t?z) and .txt file as well as build logs are created in /tmp .
# Install the package using 'installpkg' or 'upgradepkg --install-new'.
