ENH: Applying patch from bug#3443 to implement FindwxWidgets.cmake properly. It also updates the UseWX test and WXDialog sources to use the new find script.

# - Find a wxWidgets (a.k.a., wxWindows) installation.
# This module finds if wxWidgets is installed and selects a default
# configuration to use.
#
# The following variables are searched for and set to defaults in case
# of multiple choices. Change them if the defaults are not desired:
#
# wxWidgets_ROOT_DIR - Base wxWidgets directory
# (e.g., C:/wxWidgets-2.6.3).
# wxWidgets_LIB_DIR - Path to wxWidgets libraries
# (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
# wxWidgets_CONFIGURATION - Configuration to use
# (e.g., msw, mswd, mswu, mswunivud, etc.)
# wxWidgets_USE_LIBS - Libraries to use besides the common
# required ones; set to base and core by
# default. You couls also list them in
# FIND_PACKAGE(wxWidgets REQUIRED
# <components>)
#
# HAVE_ISYSTEM - if true wx warnings are suppressed on g++
# by replacing -I with -isystem
#
# The following are set after configuration is done:
#
# wxWidgets_FOUND - Set to TRUE if wxWidgets was found.
# wxWidgets_INCLUDE_DIRS - Include directories for WIN32
# i.e., where to find "wx/wx.h" and
# "wx/setup.h"; possibly empty for unices.
# wxWidgets_LIBRARIES - Path to the wxWidgets libraries.
# wxWidgets_LIBRARY_DIRS - compile time link dirs, useful for
# rpath on UNIX. Typically an empty string
# in WIN32 environment.
# wxWidgets_DEFINITIONS - Contains defines required to compile/link
# against WX, e.g. -DWXUSINGDLL
# wxWidgets_CXX_FLAGS - Include dirs and ompiler flags for
# unices, empty on WIN32. Esentially
# "`wx-config --cxxflags`".
# wxWidgets_USE_FILE - convenience include file
#
# Sample usage:
#
# SET(wxWidgets_USE_LIBS base core gl net)
# FIND_PACKAGE(wxWidgets)
# IF(wxWidgets_FOUND)
# INCLUDE(${wxWidgets_USE_FILE})
# # and for each of your dependant executable/library targets:
# TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
# ENDIF(wxWidgets_FOUND)
#
# Sample usage with monolithic wx build:
# SET(wxWidgets_USE_LIBS msw26 expat jpeg gl png regex tiff zlib)
# ...
# NOTES
#
# This module has been tested on the WIN32 platform with wxWidgets
# 2.6.2, 2.6.3, and 2.5.3. However, it has been designed to
# easily extend support to all possible builds, e.g., static/shared,
# debug/release, unicode, universal, multilib/monolithic, etc..
#
# If you want to use the module and your build type is not supported
# out-of-the-box, please contact me to exchange information on how
# your system is setup and I'll try to add support for it.

# TODO/ideas
#
# (1) Option/Setting to use all available wx libs
# In contrast to expert developer who lists the
# minimal set of required libs in wxWidgets_USE_LIBS
# there is the newbie user:
# - who just wants to link against WX with more 'magic'
# - doesn't know the internal structure of WX or how it was built,
# in particular if it is monolithic or not
# - want to link against all available WX libs
# Basically, the intent here is to mimic what wx-config would do by
# default (i.e., `wx-config --libs`).
#
# Possible solution:
# Add a reserved keyword "std" that initializes to what wx-config
# would default to. If the user has not set the wxWidgets_USE_LIBS,
# default to "std" instead of "base core" as it is now. To implement
# "std" will basically boil down to a FOR_EACH lib-FOUND, but maybe
# checking whether a minimal set was found.
#
#
# Helper macro to control the debugging output globally.
# - NOTE: This and all the DBG_MSG calls should be removed after the
# module stabilizes.
