# 20240317 bkw: update for v4.1.5.
# 20230912 bkw: update for v4.1.4.
# 20230710 bkw:
# - update for v4.1.3.
# - fail if API in env is bad (not blank, 6b, 7, or 8).
# - add zulu-openjdk11 and 17 to JDK search.
# - fail if JAVA=yes but we can't find a JDK.
# 20230105 bkw: update for v4.1.1, fix doc symlink.
# 20220318 bkw: fix 32-bit lib vs. lib32 install path mess.
# 20210909 bkw: relicense as WTFPL, w/permission from original author.
# 20210310 bkw: update for v4.0.3.
# - upstream switched from autoconf to cmake, so this script can't
# build older versions any more.
# - cmake chokes when trying to build static libs, apparently because
# we don't have a static libpng.a. So no more static libs in this
# package until further notice. If you actually care about this,
# remind me to look into it again.
# - get rid of man pages, they're identical to the ones from libjpeg-turbo.
# - add profile script.
# - add -Wl,-rpath to .pc files.
# - install HTML docs in /usr/doc.
# 20180101 bkw: Update for v3.3.1. Script still works with 3.1 and 3.2,
# if you can think of a use for them.
# 20170502 bkw:
# - update for v3.2. script tested with v3.1 and still works, in case
# upstream's updated libjpegturbo API causes a problem (just get the
# old source, run with VERSION=3.1 in the env).
# - Note: ignore the 'error: ignoring unknown tag NASM' messages, per
# https://sourceforge.net/p/libjpeg-turbo/mailman/message/34381375/
# 20170310 bkw:
# - take over maintenance
# - i486 => i586
# - build static lib also
# - expand README and slack-desc
# - add JAVA=yes option
# - add API=7 and API=8 options
# - BUILD=2
