# Slackware build script for cmake-202x

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# This build exists because the cmake in Slackware 14.2 is too old,
# and can't be upgraded. This installs cmake under /opt, where it
# won't conflict with anything. README explains how to use it in your
# SlackBuild.

# cmake.manpages.tar.lz comes from Slackware, courtesy of Pat V. Since
# it's from -current (therefore subject to change), I mirrored the
# version I'm using on slackware.uk.

# 20210306 bkw: updated for 3.19.6 (sync with -current).
# 20201108 bkw: updated for 3.18.4, put version number in manpages URL.
