FindLibKML
----------
Find the LibKML headers and libraries.
This module accept optional COMPONENTS to check supported sub modules::
LIBKML_BASE_LIBRARY
LIBKML_DOM_LIBRARY
LIBKML_ENGINE_LIBRARY
LIBKML_CONVENIENCE_LIBRARY
LIBKML_XSD_LIBRARY
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``LIBKML::LibKML``, if found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``LIBKML_FOUND``
True if libkml found.
``LIBKML_INCLUDE_DIRS``
where to find header files.
``LIBKML_LIBRARIES``
List of libraries when using libkml.
``LIBKML_VERSION_STRING``
The version of libkml found.
