# - Try to find the Exiv2 library
#
#  EXIV2_MIN_VERSION - You can set this variable to the minimum version you need
#                      before doing FIND_PACKAGE(Exiv2). The default is 0.12.
#
# Once done this will define
#
#  EXIV2_FOUND - system has libexiv2
#  EXIV2_INCLUDE_DIR - the libexiv2 include directory
#  EXIV2_LIBRARIES - Link these to use libexiv2
#  EXIV2_DEFINITIONS - Compiler switches required for using libexiv2
#
# The minimum required version of Exiv2 can be specified using the
# standard syntax, e.g. find_package(Exiv2 0.17)
#
# For compatibility, also the variable EXIV2_MIN_VERSION can be set to the minimum version
# you need before doing FIND_PACKAGE(Exiv2). The default is 0.12.
