+UsewxWidgets
+------------
+
+Convenience include for using wxWidgets library.
+
+Determines if wxWidgets was FOUND and sets the appropriate libs,
+incdirs, flags, etc.  INCLUDE_DIRECTORIES and LINK_DIRECTORIES are
+called.
+
+USAGE
+
+::
+
+  # Note that for MinGW users the order of libs is important!
+  find_package(wxWidgets REQUIRED net gl core base)
+  include(${wxWidgets_USE_FILE})
+  # and for each of your dependent executable/library targets:
+  target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
+
+
+
+DEPRECATED
+
+::
+
+  LINK_LIBRARIES is not called in favor of adding dependencies per target.
