Is there a way to adjust lookup paths for modules during compilation?

I'm not doing IO. I'm looking for something like this:
version(version1) {
  add_import_path("location1");
}
else version(version2) {
  add_import_path("location2");
}

And dozens of other modules that do simple 'import somemodule' 
will get this module from either location1 or location2.
