-dnl
-dnl Test for wxWidgets, and define WX_C*FLAGS, WX_LIBS and WX_LIBS_STATIC
-dnl (the latter is for static linking against wxWidgets). Set WX_CONFIG_NAME
-dnl environment variable to override the default name of the wx-config script
-dnl to use. Set WX_CONFIG_PATH to specify the full path to wx-config - in this
-dnl case the macro won't even waste time on tests for its existence.
-dnl
-dnl Optional WX-LIBS argument contains comma- or space-separated list of
-dnl wxWidgets libraries to link against (it may include contrib libraries). If
-dnl it is not specified then WX_LIBS and WX_LIBS_STATIC will contain flags to
-dnl link with all of the core wxWidgets libraries.

-dnl Optional ADDITIONAL-WX-CONFIG-FLAGS argument is appended to wx-config
-dnl invocation command in present. It can be used to fine-tune lookup of
