#
# 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_LIBRARY         = full path to the wxWindows library and linker flags on unix
#  CMAKE_WX_CXX_FLAGS        = compiler flags for building wxWindows 
#  WXWINDOWS_INCLUDE_PATH    = include path of wxWindows
