-## 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.

-## -removed OPTION for CMAKE_WXWINDOWS_USE_GL. Force the developer to SET it.

-##    2002 (static build)
