More specifically, this eclass controls the configuration chosen by the
/usr/bin/wx-config wrapper.
Using the eclass is simple:
- set WX_GTK_VER equal to a SLOT of wxGTK
- call setup-wxwidgets()
The configuration chosen is based on the version required and the flags
wxGTK was built with.
Call this in your ebuild to set up the environment for wxGTK. Besides
controlling the wx-config wrapper this exports WX_CONFIG containing
the path to the config in case it needs to be passed to a build system.
In wxGTK-2.9 and later it also controls the level of debugging output
from the libraries. In these versions debugging features are enabled
by default and need to be disabled at the package level. Because this
causes many warning dialogs to pop up during runtime we add -DNDEBUG to
CPPFLAGS to disable debugging features (unless your ebuild has a debug
USE flag and it's enabled). If you don't like this behavior you can set
WX_DISABLE_NDEBUG to override it.
