+# - Find a wxWidgets (a.k.a., wxWindows) installation.
+# This module finds if wxWidgets is installed and selects a default
+# configuration to use. wxWidgets is a modular library. To specify the
+# modules that you will use, you need to name them as components to
+# the package:
+#
+# find_package(wxWidgets COMPONENTS core base ...)
+#
+# There are two search branches: a windows style and a unix style. For
+# windows, the following variables are searched for and set to
+# defaults in case of multiple choices. Change them if the defaults
+# are not desired (i.e., these are the only variables you should
+# change to select a configuration):
+#
+#  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_EXCLUDE_COMMON_LIBRARIES
+#                          - Set to TRUE to exclude linking of
+#                            commonly required libs (e.g., png tiff
+#                            jpeg zlib regex expat).
+#
+# For unix style it uses the wx-config utility. You can select between
+# debug/release, unicode/ansi, universal/non-universal, and
+# static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
+# the following variables:
+#
+#  wxWidgets_USE_DEBUG
+#  wxWidgets_USE_UNICODE
+#  wxWidgets_USE_UNIVERSAL
+#  wxWidgets_USE_STATIC
+#
+# There is also a wxWidgets_CONFIG_OPTIONS variable for all other
+# options that need to be passed to the wx-config utility. For
+# example, to use the base toolkit found in the /usr/local path, set
+# the variable (before calling the FIND_PACKAGE command) as such:
+#
+#  set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)
+#
+# The following are set after the configuration is done for both
+# windows and unix style:
+#
+#  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. WXUSINGDLL
+#  wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
+#                               against WX debug builds, e.g. __WXDEBUG__
+#  wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
+#                               unices, empty on WIN32. Essentially
+#                               "`wx-config --cxxflags`".
+#  wxWidgets_USE_FILE         - Convenience include file.
+#
+# Sample usage:
+#   # Note that for MinGW users the order of libs is important!
+#   find_package(wxWidgets COMPONENTS net gl core base)
+#   if(wxWidgets_FOUND)
+#     include(${wxWidgets_USE_FILE})
+#     # and for each of your dependent executable/library targets:
+#     target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
+#   endif(wxWidgets_FOUND)
+#
+# If wxWidgets is required (i.e., not an optional part):
+#   find_package(wxWidgets REQUIRED net gl core base)
+#   include(${wxWidgets_USE_FILE})
+#   # and for each of your dependent executable/library targets:
+#   target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
+#
+# If a wxWidgets version or greater is required:
+#   find_package(wxWidgets 2.8.12 COMPONENTS net gl core base REQUIRED)
+#
+# If specific wxWidgets version is required:
+#   find_package(wxWidgets 2.8.12 EXACT COMPONENTS net gl core base REQUIRED)

+# 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.
+
+
