##
## This module finds if wxWindows 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 (in desired config. build)
##
## WXWINDOWS_LIBRARIES = full path to the wxWindows libraries
## on Unix/Linux with additional linker flags from
## "wx-config --libs"
##
## CMAKE_WXWINDOWS_CXX_FLAGS = Unix compiler flags for wxWindows, essentially
## "`wx-config --cxxflags`"
##
## WXWINDOWS_INCLUDE_DIR = where to find headers "wx/wx.h" "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
##
## ------------------------------------------------------------------
##
## USAGE:
## # for convenience include Use_wxWindows.cmake in your projects
## CMakeLists.txt:
##
## # if you need OpenGL support please
## SET(WXWINDOWS_USE_GL 1)
## # in your CMakeLists.txt *before* you include this file.
##
## # just include Use_wxWindows.cmake
## # in your projects CMakeLists.txt
## INCLUDE(Use_wxWindows)

## -changed variable names to conventions from cmakes readme.txt (Jan Woetzel
## 07/07/2003)
## -added definition WINVER for WIN32 (Jan Woetzel 07/07//2003)
## -added IF(CMAKE_WXWINDOWS_CONFIG_EXECUTABLE) found and changed
## CMAKE_WX_CONFIG to CMAKE_WXWINDOWS_CONFIG_EXECUTABLE (Jan Woetzel
## 07/22/2003)
## -removed OPTION for CMAKE_WXWINDOWS_USE_GL. Force the developer to SET it.
##
## status:
## tested with:
## -cmake 1.6.7, Linux (Suse 7.3), wxWindows 2.4.0, gcc 2.95
## -cmake 1.6.7, Linux (Suse 8.2), wxWindows 2.4.0, gcc 3.3
## -cmake 1.6.7, Linux (Suse 8.2), wxWindows 2.4.1-patch1, gcc 3.3
## -cmake 1.6.7, MS Windows XP home, wxWindows 2.4.1, MS Visual Studio .net 7
## 2002 (static build)
##
## TODO:
## -OPTION for unicode builds
## -change WXWINDOWS_USE_GL to use FindOpenGL.cmake or let the user do it
## -testing of DLL linking under MS WIN32
