[KPhotoAlbum] [KPhotoAlbum 5.0.1] Compilation error without libkexiv2

[Bruno Pagani]

Hi,

While trying to determine the required dependencies (which, on
ArchLinux, happen to be KF5 variants of the old KDE4 libs used + exiv2,
although all are optional, and libkexiv2 as a build-time dependency, but
not runtime apparently), I’ve stumbled upon this when trying to build
without libkexiv2 although this library only appears under RECOMMENDED
packages and not REQUIRED ones:

Note that I’m going to build it with libkexiv2 anyway, but thought I
would mention it here just in case.

Thanks for your awesome work on porting KPhotoAlbum BTW! :)
