Added wxWidget related cmake files to make crosscompiling possible

# - 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.
