# Finduuid
# -----------
#
# Find libuuid, DCE compatible Universally Unique Identifier library.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``UUID_FOUND``
# True if libuuid has been found.
# ``UUID_INCLUDE_DIRS``
# Where to find uuid/uuid.h.
# ``UUID_LIBRARIES``
# The libraries to link against to use libuuid.
#
# Obsolete variables
# ^^^^^^^^^^^^^^^^^^
#
# The following variables may also be set, for backwards compatibility:
#
# ``UUID_LIBRARY``
# where to find the libuuid library (same as UUID_LIBRARIES).
# ``UUID_INCLUDE_DIR``
# where to find the uuid/uuid.h header (same as UUID_INCLUDE_DIRS).
