I must not understand the use case.  It looks to me like you're generating
a <pkg>Targets.cmake file to be loaded by a <pkg>Config.cmake file.  If
these files are being read then <pkg>_DIR is set to a copy of the <pkg>.
The package has been found.  Just as in the previous discussion, the
error in the package occurs because it is misconfigured: one of its
dependencies is not installed or loaded correctly to provide the other
imported target.
