I'm already aware of the distinction. Granted, UseQt4.cmake doesn't know if
imported targets are being used or not, and probably cannot be reduced to the
public dependencies.
But, aren't you still missing the private dependencies so that the -rpath-link
flag (for Linux/GNU) can be added to specify the location of the private
dependencies?
Maybe we can always use imported targets in FindQt4.cmake, then end up with one
place to specify public & private dependencies.
