# - 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 base core ...)
# 
# 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
#  
# 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:
#   FIND_PACKAGE(wxWidgets COMPONENTS base core gl net)
#   IF(wxWidgets_FOUND)
#     INCLUDE(${wxWidgets_USE_FILE})
#     # and for each of your dependent executable/library targets:
#     TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
#   ENDIF(wxWidgets_FOUND)
#
# If wxWidgets is required (i.e., not an optional part):
#   FIND_PACKAGE(wxWidgets REQUIRED base core gl net)
#   INCLUDE(${wxWidgets_USE_FILE})
#   # and for each of your dependent executable/library targets:
#   TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})

# 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.
