+Subject: [PATCH 2/2] Fix build with exiv2-0.27
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Summary:
+Include exiv2.hpp instead of individual headers
+
+Headers are subject to refactoring upstream, using exiv2.hpp per recommendation.
+
+Enable exceptions globally - otherwise, lots of the following error:
+
+In file included from /usr/include/exiv2/types.hpp:34,
+                 from /usr/include/exiv2/image.hpp:28,

+                 from gwenview-18.12.0/lib/cms/cmsprofile.cpp:22:
+/usr/include/exiv2/slice.hpp: In constructor ‘Exiv2::Internal::SliceBase::SliceBase(size_t, size_t)’:
+/usr/include/exiv2/slice.hpp:99:77: error: exception handling disabled, use -fexceptions to enable
+                     throw std::out_of_range("Begin must be smaller than end");
+                                                                             ^
