I don't have tried to compile your code, but I'm pretty sure that it
isn't a compilation error, but a runtime error.

Yes (plugin _interfaces_) :D

Sure !

In this case you must have a library that does the common function for
all plugins.

Could you post also the .pro file? Just for curiosity.
Also, don't use .load(), see the example: [1] that use

QPluginLoader pluginLoader(pluginDirectory.absoluteFilePath(fileName));
     QObject *plugin = pluginLoader.instance();
     if (plugin) {
         ....
