[arch-dev-public] wxgtk split

[Antonio Rojas]

Hi,
 As you may have noticed, the wxgtk package is now a split package that 
build both gtk2 and gtk3 versions. The gtk2 package is a drop-in 
replacement for the old wxgtk package, so by default all packages will 
keep building against gtk2.

 If you maintain a wx-based package, you may want to try switching to 
build against wxgtk3, which offers some additional features (hipdi, smooth 
scrolling, touchscreen support).

 To allow coinstallability, the wx-config script has been renamed to wx-
config-gtk3 in the GTK3 package, so in order to build against the gtk3 
version the script name needs to be specified at build time (--with-wx-
config=/usr/bin/wx-config-gtk3 for autotools, -
DwxWidgets_CONFIG_EXECUTABLE=/usr/bin/wx-config-gtk3 for cmake)
