Subject: [PATCH 4/9] cmComputeLinkInformation: compute link info for
 module-using targets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Targets which contain C++ module or Fortran sources need to participate
in link information unconditionally regardless of whether they actually
have link artifacts or not.

Fixes: #25223
