# Slackware build script for jfbview

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

# This doesn't depend on mupdf or mupdf-legacy because it includes its
# own bundled mupdf source.

# 20260719 bkw:
# - update for v0.7.0.
# - upstream no longer requires imlib2 for image viewing, so get rid
#   of all mentions of it.

# 20230104 bkw: BUILD=2
# - fix imlib2 builds (broke with recent imlib2 update to 1.10.0).
# - fix PKGTYPE mess.

# compile # commands? make VERBOSE=1 doesn't work, neither does
# CMAKE_VERBOSE_MAKEFILE=ON. I would like to know if the SLKCFLAGS are
# actually used... I can look at the output of "ps auxwww", it's just
# annoying. And the answer is, no they are not. Sigh.
