# Slackware build script for whdd
#
# Upstream: https://github.com/whdd/whdd
# No SlackBuilds.org entry and not in Debian. Tag 3.1 is the newest
# upstream release; Parted Magic previously shipped a 2.2 snapshot
# converted from an Ubuntu package.
#
# CMake 4 removed compatibility with cmake_minimum_required < 3.5 and
# whdd's CMakeLists.txt asks for 2.8.4, hence CMAKE_POLICY_VERSION_MINIMUM.
#
# BUILD DEPENDENCY: libdialog. Slackware's dialog package ships only the
# binary, so libdialog.a and its headers must be present at build time:
#   configure && make libdialog.a in Slackware's dialog source, then
#   install libdialog.a into /usr/lib64 and dialog.h, dlg_*.h into
#   /usr/include. Only the static lib is needed -- whdd then carries no
#   runtime dependency on dialog, which is how the old Ubuntu-derived
#   package was linked too.
