dnl ---------------------------------------------------------------------------
dnl AM_PATH_WXCONFIG(VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND
dnl [, WX-LIBS [, ADDITIONAL-WX-CONFIG-FLAGS]]]])
dnl
dnl Test for wxWindows, and define WX_C*FLAGS, WX_LIBS and WX_LIBS_STATIC
dnl (the latter is for static linking against wxWindows). 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 wxWindows 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 wxWindows libraries.
dnl
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
dnl best wxWidgets build available.
dnl
dnl Example use:
dnl AM_PATH_WXCONFIG([2.6.0], [wxWin=1], [wxWin=0], [html,core,net]
dnl [--unicode --debug])
