This causes a downgrade of imagemagick on my testing system which in turn causes issues elsewhere.
Seems the API of ImageMagick has changed and this library no longer compiles, see https://github.com/OpenShot/libopenshot/issues/60
Fixed the bug report to describe this properly. Seems the latest ImageMagick 7.x changed it's API and libopenshot fails to build with it.
Created attachment 486924 [details] Build failure
