Flatpak: unresolved symbols, plugin does not load.

Trying to use the current builds at cloudsmith.io I get the following in the logfile:

17:38:05.322 MESSAGE pluginmanager.cpp:1167 Found 2 candidates

Practical result is that plugin does not load and is unusable.

This could probably be fixed by following patch, which bundles tinyxml on all platforms:

I find it hard to work with the testplugin setup. Hopefully , someone skilled could test this patch.

Fixed in #9. Closing.
