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.
