# 20241017 bkw: BUILD=2, update for lua 5.4.
# - no changes; just bump BUILD so people know to rebuild it.

# 20230716 bkw: update for v3.2.4.
# 20220616 bkw: update for v3.2.1.

# 20220208 bkw:
# - grr. add missing 'fmt' dep. my bad.
# - autodetect wxWebView support in wxGTK3. also my bad.

# 20211118 bkw:
# - update for v3.2.0_b3. normally won't package a beta, but
#   3.1.12a and 3.1.13 won't build, and life is too short.
# - our wxGTK3 now has wxWebView, get rid of -DNO_WEBVIEW.
# - /usr/share/slade3 moved to /usr/share/games/slade3.
# - new- and old-style icons.
# - add p7zip dep (the build process recompresses the .pk3).

# 20201109 bkw: update for v3.1.12a
# 20200416 bkw:
# - take over maintenance
# - update for v3.1.11
# - binary in /usr/games
# - install icon in right place, symlink to old location
# - get rid of our .desktop file (upstream provides one now)

# 20200416 bkw: don't depend on unstable /usr/bin/wx-config symlink.
# stupid thing insists on searching for wx-config in PATH, instead of
# allowing us to explicitly give a full path and name for the script, so:
WXCONF=/usr/lib$LIBDIRSUFFIX/wx/config/gtk3-unicode-3.2
WXTMP=$( pwd )/wxtmp
mkdir -p $WXTMP
ln -s $WXCONF $WXTMP/wx-config

# Note to self: don't try this:
#    -DCMAKE_C_COMPILER=clang \
#    -DCMAKE_CXX_COMPILER=clang++ \
# It might compile OK but it will fail to run due to C++ ABI
# version differences between the slade binary and the wx libraries.
# We'd have to compile wxGTK3 with clang++ to make it work (and that
# would break everything else using g++ and wxGTK3!)

# Also, this build isn't ccache-able due to using precompiled headers
# with g++ (see overly detailed discussion in games/mame). It's possible
# to disable PCH, thus:
#    -DNO_COTIRE=ON \
# but this makes the build take 3x as long, if it's not cached. Since
# a non-ccached build with cotire only takes me 5 minutes, I won't go
# to extreme lengths here like I did for mame.

# 20220208 bkw: I screwed up: I forgot wxGTK3 isn't always built with
# webkit2gtk (so it doesn't always have wxWebView). slade doesn't
# autodetect this, so detect it ourselves:
# 20240928 bkw: Upstream upgraded to wx-3.2, meaning this now uses
# wxWidgets rather than wxGTK3. Currently, webkit2gtk is listed
# as a hard dep for wxWidgets, but this is actually incorrect: if
# wxWidgets is built without webkit2gtk installed, it'll build fine,
# minus wxWebView support, just like wxGTK3 would. This means wxWidgets
# should be (and likely will be) changed so that webkit2gtk becomes an
# optional dep... in which case, this code still applies:
