# FindCanberra
# ------------
#
# Try to find Canberra event sound library.
#
# This will define the following variables:
#
# ``Canberra_FOUND``
#     True if (the requested version of) Canberra is available
# ``Canberra_VERSION``
#     The version of Canberra
# ``Canberra_LIBRARIES``
#     The libraries of Canberra for use with target_link_libraries()
# ``Canberra_INCLUDE_DIRS``
#     The include dirs of Canberra for use with target_include_directories()
#
# If ``Canberra_FOUND`` is TRUE, it will also define the following imported
# target:
#
# ``Canberra::Canberra``
#     The Canberra library
#
# In general we recommend using the imported target, as it is easier to use.
# Bear in mind, however, that if the target is in the link interface of an
# exported library, it must be made available by the package config file.
#
# Since 5.56.0.
