# - Convenience include for using wxWidgets library
# Finds if wxWidgets is installed 
# and set the appropriate libs, incdirs, flags etc. 
# INCLUDE_DIRECTORIES, LINK_DIRECTORIES and ADD_DEFINITIONS
# are called.
#
# USAGE
#  SET( wxWidgets_USE_LIBS  gl xml xrc ) # optionally: more than wx std libs
#  FIND_PACKAGE(wxWidgets REQUIRED)
#  INCLUDE( ${xWidgets_USE_FILE} )
#  ... add your targets here, e.g. ADD_EXECUTABLE/ ADD_LIBRARY ...
#  TARGET_LINK_LIBRARIERS( <yourWxDependantTarget>  ${wxWidgets_LIBRARIES})
# 
# DEPRECATED
#  LINK_LIBRARIES is not called in favor of adding dependencies per target.
