#.rst:
# FindLibExiv2
# ------------
#
# Try to find the Exiv2 library.
#
# This will define the following variables:
#
# ``LibExiv2_FOUND``
# True if (the requested version of) Exiv2 is available
#
# ``LibExiv2_VERSION``
# The version of Exiv2
#
# ``LibExiv2_INCLUDE_DIRS``
# The include dirs of Exiv2 for use with target_include_directories()
#
# ``LibExiv2_LIBRARIES``
# The Exiv2 library for use with target_link_libraries().
# This can be passed to target_link_libraries() instead of
# the ``LibExiv2::LibExiv2`` target
#
# If ``LibExiv2_FOUND`` is TRUE, it will also define the following imported
# target:
#
# ``LibExiv2::LibExiv2``
# The Exiv2 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 5.53.0.
