One possibility would be introducing a path discovery system through sysconf or
similar, so that applications could query the system for the path prefix to be
used instead of using compile-time configured paths. Environment variables
exist but that might not be a good solution, an admin might really want to have
control over the paths used.

I'd think the most important and actively developed applications would support
such a simple feature in no time. Of course on many popular systems this
problem does not exist because everything is simply thrown into

Maybe this could be integrated into pkg-config actually. The API would be
as simple as this:

const char *package_config_get_path_prefix(const char *package_name);

or possibly support different paths for icons, shared data and such. Albeit
you can probably just use symlinks for the same purpose, so this would be
