--- Description ---
After last exiv updates, compiling gwenview with GCC8 fails:

documentimpl.cpp:28:
/usr/local/include/exiv2/slice.hpp: In constructor
'Exiv2::Internal::SliceBase::SliceBase(size_t, size_t)':
/usr/local/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");
									     ^

Add -fexceptions to CXXFLAGS when using GCC to fix it.
