Hi Mojca:

Just to clarify there has been a change in the CMake bugtracker.  You
reference the old bug tracker entry where all issues there were
automatically closed and moved to the new bug tracker
<https://gitlab.kitware.com/cmake/cmake/issues/14252>. However, that
is an almost completely vacuous entry (except for title) in the new
bug tracker although it does declare the issue is still open. As far
as I can tell from that old discussion, Brad King found the hard-coded
source of your problem in the CMake code with -arch, but there is no
reference to a fix either in the old tracker or new one so I assume
that fix has not been implemented yet.

Furthermore, although there is a superficial resemblance I am pretty
sure from the description this hard-coded issue is quite specific to
certain compiler options, and does not refer to ignoring all nagfor
compiler options as Arjen has apparently observed. So I think the
source of Arjen's problem likely is that he is using the incorrect
Platform filenames for the various nagfor Windows cases that have been
discussed, and we need advice from a CMake language support expert to
help us figure out what those Platform filenames should be.
