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

Usage:
    Options WX_CPPFLAGS, WX_CFLAGS, WX_CXXFLAGS, WX_LIBS are defined.


Format-specific notes:

* autoconf:
        Beware that you have to use AM_OPTIONS_WXCONFIG and
        AM_PATH_WXCONFIG in your configure.in!

         We need to re-define the resource compiler, used by bakefile when compiling
         resources, to the resource compiler returned by 'wx-config &#45;-rescomp' since
         'wx-config &#45;-rescomp' returns both the name of the resource compiler to use
         and the flags required for that compiler (rcflags are rccompiler-specific
         and thus it would be wrong to use them with other resource compilers).

         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).

         NOTE: overwriting the RESCOMP variable we modify the entire Bakefile behaviour
               for resource compilation; this could be a problem if the bakefile which
               includes this file needs the standard Bakefile resource compiler to
               build a non wx-based application.
