CMake/Modules/FindwxWindows.cmake

# - Find wxWindows (wxWidgets) installation 
# This module finds if wxWindows/wxWidgets is installed and determines where 
# the include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#  
#  WXWINDOWS_FOUND     = system has WxWindows 
#  WXWINDOWS_LIBRARIES = path to the wxWindows libraries
#                        on Unix/Linux with additional 
#                        linker flags from 
#                        "wx-config --libs"
#  CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows, 
#                               essentially "`wx-config --cxxflags`"
#                               on Linux
#  WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
#  WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
#                                Unix
#  WXWINDOWS_DEFINITIONS      = extra defines
# 
# DEPRECATED
#  CMAKE_WX_CAN_COMPILE
#  WXWINDOWS_LIBRARY
#  CMAKE_WX_CXX_FLAGS
#  WXWINDOWS_INCLUDE_PATH
#
# OPTIONS 
# If you need OpenGL support please 
#  SET(WXWINDOWS_USE_GL 1) 
# in your CMakeLists.txt *before* you include this file.
# 
# For convenience include Use_wxWindows.cmake in your project's
# CMakeLists.txt using INCLUDE(Use_wxWindows). 
# 
# USAGE 
#  SET(WXWINDOWS_USE_GL 1) 
#  FIND_PACKAGE(wxWindows)
# 
# NOTES
# wxWidgets 2.6.x is supported for monolithic builds 
# e.g. compiled  in wx/build/msw dir as:  
#  nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1
