Thank you for the hint, and I run in a similiar problem. Building from
scratch solved the issue.
Sorry for the noise.

This could be a case of needing to clear out an old CMake cache. That
problem you mentioned was supposed to have been fixed already. You can
find the updated discussion of the Mantis issue you linked to in
gitlab here
<https://gitlab.kitware.com/cmake/cmake/issues/11881> where someone
else had a situation that sounds similar to yours.

Dear all,
recently, I got a problem with FindMPI on our HPC systems. With
cmake 3.10.2, I get an error about policy CMP0004. And I cannot
set it to OLD anymore. Is this intended?
Exactly the same error, together with a patch, is described in the
bugtracker https://public.kitware.com/Bug/view.php?id=11881
<https://public.kitware.com/Bug/view.php?id=11881>
I cannot reproduce the error easiliy. On my home system, it works.
But on the hpc system, mpicc -showme:link returns
-L<MPIDIR>/lib -lmpi -ldl -lm -lnuma -Wl,--export-dynamic -lrt
-lnsl -lutil -lm -ldl
so, we have exactly one -Wl,<something> part and libraries
otherwise. It looks to me, that the patch from the bugtracker
should avoid the problem.
Can somebody confirm this finding?
The problem gets even worse with newercmake versions. With cmake
3.9, I can set policy cmp0004 to OLD, so FindMPI remains usable.
With newer cmake versions, ie. 3.10.2, the policy setting seems
to get deprecated. So, the user won't get any way to use newer
cmake with such a bug.
What is the preferred way to resolve such an issue, when the
policy setting is not allowed anymore?
Regards,
Andreas
