Why not simply use install(FILES ... PERMISSIONS .... RENAME ...  )?

You would have to use the target property LOCATION to find the
(cross-platform) filename associated with the target, and you would have to
specify the appropriate PERMISSIONS, but I think this method of using
install(FILES ...) should work fine unless and until a feature request for a
RENAME option for install(TARGETS....) is implemented.
