strigi does not handle dependencies correctly

[barracuda156]

strigi is supposed to use log4cxx, but does not declare dependency on it. Also, exiv2 is not found correctly and in result gets disabled.

In fact it fails to build with log4cxx found with multiple errors, so it rather should be disabled.

strigi's FindExiv2.cmake tries to extract the exiv2 version number from exiv2's version.hpp header. The components of the version number aren't defined in that header anymore ​ever since exiv2 0.27. The strigi web site says ​strigi bugs should be reported here but it doesn't look like anybody has reported anything since 2015. The repository browse link at sourceforge doesn't work. I found a copy of the ​strigi repository here but it doesn't have any commits after 2016. ​Wikipedia says strigi has been replaced by recoll.

KDE4 is not developed anymore, so anything which is KDE4-specific is unlikely to get upstream updates. However, a) that’s the only KDE MacPorts has at the moment and b) KDE5 will obviously require Qt5, which is broken on a number of legacy systems (until someone fixes it).
