FindLibUUID
------------

Find LibUUID include directory and library.

Imported Targets
^^^^^^^^^^^^^^^^

An :ref:`imported target <Imported targets>` named
``LibUUID::LibUUID`` is provided if LibUUID has been found.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``LibUUID_FOUND``
  True if LibUUID was found, false otherwise.
``LibUUID_INCLUDE_DIRS``
  Include directories needed to include LibUUID headers.
``LibUUID_LIBRARIES``
  Libraries needed to link to LibUUID.

Cache Variables
^^^^^^^^^^^^^^^

This module uses the following cache variables:

``LibUUID_LIBRARY``
  The location of the LibUUID library file.
``LibUUID_INCLUDE_DIR``
  The location of the LibUUID include directory containing ``uuid/uuid.h``.

The cache variables should not be used by project code.
They may be set by end users to point at LibUUID components.
