Presents for building wxWidgets applications using Autoconf or GNU toosets.
See wx.bkl for platform-independent notes.

Format-specific notes:

* autoconf:
        Beware that you have to use AM_OPTIONS_WXCONFIG and
        AM_PATH_WXCONFIG in your configure.in to get at least the
        WX_CPPFLAGS, WX_CFLAGS, WX_CXXFLAGS, WX_LIBS option values defined.
        To detect the WX_* option values typically you also want to use
        the AM_WXPRESETS_OPTIONS and AM_WXPRESETS_CHECKS macros
        (see wxpresets.m4 for more info).

         We need to re-define the WINDRES resource compiler name to the resource compiler
         returned by 'wx-config - -rescomp' since this option returns both the name of the
         resource compiler to use (windres) and the flags required for that compiler.

         This line typically does something *only* when the Makefile.in generated
         using this bakefile, is used on Windows with MSYS (when using Cygwin, resources
         are not compiled at all).
         Without this line, in fact, when compiling with MSYS on Windows, the - -include-dir
         option which tells windres to look in wxWidgets\include folder would be missing and
         then windres would fail to find the wxMSW resources.

         NOTE: overwriting the WINDRES variable we add wxWidgets resource flags to
               all targets which include this bakefile; this could be useless to those
               targets which are not wx-based eventually present in that bakefile but
               in any case it shouldn't do any harm.
