Finds ``icotool``, command-line program for converting and creating Win32 icon
and cursor files.

``Icotool_FOUND``
True if ``icotool`` has been found. For backward compatibility, the
``ICOTOOL_FOUND`` variable is also set to the same value.
``ICOTOOL_VERSION_STRING``
The version of ``icotool`` found.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``ICOTOOL_EXECUTABLE``
The full path to the ``icotool`` tool.
Examples
^^^^^^^^
Finding ``icotool`` and executing it in a process to create ``.ico`` icon from
the source ``.png`` image located in the current source directory:
.. code-block:: cmake
find_package(Icotool)
if(Icotool_FOUND)
execute_process(
COMMAND
${ICOTOOL_EXECUTABLE} -c -o ${CMAKE_CURRENT_BINARY_DIR}/img.ico img.png
)
endif()
