<!--
    Presets for building wxWidgets applications.

    These presets provide the following "public" interface:

    OPTIONS:

    - WX_* : used to let the user of the generated makefile choose a wxWidgets
             build among those available; you can use them in your project to
             e.g. build a target only if WX_SHARED is 0 or if WX_PORT is "msw".


    VARIABLES:

    - WXLIBPOSTFIX: contains the [u][d] string which is typically useful when
                    defining names of directories/files which should coexist
                    with other builds using different wxWidgets configurations.


    TEMPLATES:

    - wx, wx-lib: templates to be used respectively for <dll>/<exe> and <lib>
                  targets; they add all the wxWidgets-related settings (e.g. the
                  include and library search paths, the necessary preprocessor
                  symbols, etc).

    - wxgui: to be used when building GUI-mode applications.

    - wxconsole: to be used when building console-only applications
                 (NOTE: it doesn't add the wxUSE_GUI=0 define since you don't
                 need it when compiling wxBase-only code).

    - wxlike: this template should be combined with "wx" or "wx-lib" and will
              make your project build with the same Unicode & shared
              config as the wxWidgets build selected using the WX_* options.


    TARGET TAGS:

    - <wx-lib>: to define which wxWidgets libraries to link with;
                please note that you should use them in the right order or
                linking under Unix would result in errors, e.g.

                    <wx-lib>core</wx-lib>
                    <wx-lib>base</wx-lib>

                is correct, but the reverse is not (if lib A depends on lib B, then
                lib A must be listed before B). So <wx-lib>base</wx-lib>
                (which must always be present) should be the last wx-lib tag.

    - <wxlike-libname>,
      <wxlike-dllname>: useful if you want to have a build logic similar to the
                        wxWidgets build logic which allows different builds to
                        coexist without conflicts. These tags helps you to name
                        libraries using the same wxWidgets rules and thus avoid
                        conflicts between libraries compiled in e.g. Unicode,
                        shared mode and those compiled in ANSI, shared mode &c.

    - <wxlike-lib>: if your library/application needs to link with both
                    wxWidgets and some other wx-based library, which in turn
                    follows the wxWidgets naming conventions, then this tag is
                    what you need to reference the wx-based additional library.

    - <wxlike-dirname>: sets the output directory for the current target to $(value)
                        when on Unix and to e.g. $(value)/vc_lib when on Windows,
                        i.e. acts like <dirname> just following wxWidgets naming rules.
                        Useful to allow multiple builds of the

    - <wxlike-paths>: if your library/application needs to compile & link with both
                      wxWidgets and some other wx-based library, which in turn
                      follows the wxWidgets naming conventions, then this tag is
                      what you need to add to the compiler and linker flags the paths
                      of the "include" and "lib" folders of the wx-based additional library.


    GLOBAL TAGS:

    - <set-wxlike-builddir>: sets BUILDDIR using wxWidgets naming rules to help
                             to keep object files compiled with different
                             settings separate.

    - <set-wxlike>: sets a variable with the name of a library named with the same
                    wxWidgets rules.

                     This is required because some compilers (e.g. MSVC) need to store in the
                     output folder some files (e.g. the PDB file) while compiling and thus
                     the library output folder must have been created before _any_ source file
                     is compiled, not just before the library is linked.
