    The link interface of MODULE libraries is empty (#11945)
    
    MODULE libraries cannot be linked into other libraries and executables
    (just like executables without ENABLE_EXPORTS).  Set the MODULE target
    link interface to be empty.  This allows such targets to be installed in
    an EXPORT set without including all their private implementation
    dependencies.
