dnl Test for wxWindows, and define WX_C*FLAGS, WX_LIBS and WX_LIBS_STATIC

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.
