// TODO... this is right now just a nasty hack.
// This should search one or multiple directories for all plugins it can
// find (to this end, we maybe should use a special prefix/suffix; e.g.

// The list of directories to search could be e.g.:
// User specified (via config file), ".", "./plugins", "$(prefix)/lib".

// We also need to add code which ensures what we are looking at is
// a) a ScummVM engine and b) matches the version of the executable.
// Hence one more symbol should be exported by plugins which returns
// the "ABI" version the plugin was built for, and we can compare that
// to the ABI version of the executable.
// Load all plugins.
