# 20240815 bkw: lv2 is supposed to be autodetected, but if it's
# missing, the build fails unless we explicitly disable. So:
LV2_OPT="OFF"

# This thing can't be told to use qmake-qt5, and keeps choking on
# /usr/bin/qmake. The --with-qt option doesn't help, only putting
# qt5's bin/ before /usr/bin in $PATH will do.

# 20240925 bkw: Add -DCONFIG_QT6=0, to avoid it autodetecting and
# using qt6 if installed. Not interested in dealing with it, and the
# qt5 UI works fine.

# 20180702 bkw: big long block of notes-to-self (and hopefully others):

# Upstream ships a French man page, but installs it in the wrong place.

# The Slackware situation with character sets and man pages confusing to
# begin with, and is in flux because post-14.2 -current has switched to
# using man-db. A lot of Slackware packages (not just SBo ones) get this
# stuff wrong.

# For 14.2, using old-school man, the man page has to be in ISO-8859-1,
# in the /usr/man/fr/ directory. This works for LANG=fr_FR (page is
# used as-is) and also LANG=fr_FR.UTF-8 (man command converts it to
# UTF-8 for displaying). Old-school man doesn't even look for a
# /usr/man/fr.UTF-8/ dir at all.

# 15.0, using man-db, works the opposite way: the man page should be
# in UTF-8, stored in /usr/man/fr.UTF-8/, and will be used as-is if
# LANG=fr_FR.UTF-8. If LANG=fr_FR, man-db will convert it to ISO-8859-1
# for display.

# The situation is even worse if you speak e.g. Japanese: I haven't found
# a way to make 14.2's man display Japanese at all (which is one of the
# reasons 15.0 will be using man-db actually).

# For this build, upstream's French man page is UTF-8, so for 14.2 we have
# to convert it to ISO-8859-1 here. When updating this script for 15.0,
# we'll be able to get rid of the conversion (and most of this comment
# block!) and ship only the UTF-8 man page. For now, include both,
# to be -current-friendly.
