++# ------------

++# Try to find the Exiv2 library.

++# This will define the following variables:
++#
++# ``LibExiv2_FOUND``
++#     System has LibExiv2.
++#
++# ``LibExiv2_VERSION``
++#     The version of LibExiv2.
++#
++# ``LibExiv2_INCLUDE_DIRS``
++#     This should be passed to target_include_directories() if
++#     the target is not used for linking.
++#
++# ``LibExiv2_LIBRARIES``
++#     The LibExiv2 library.
++#     This can be passed to target_link_libraries() instead of
++#     the ``LibExiv2::LibExiv2`` target
++#
++# If ``LibExiv2_FOUND`` is TRUE, the following imported target
++# will be available:
++#
++# ``LibExiv2::LibExiv2``
++#     The Exiv2 library
++#
++# Since 5.53.0.
