Build with PARmetis on Windows fails

[j-machacek]

Dear scivison,

its me again - this time with Parmetis.

I am running in similar problems as for metis before your fix.

To build a parallel version of mumps I changed the build.bat file by adding a new variable parmetis to it as follows:

...

REM use Metis?
set metis=0
set parmetis=1

REM use Scotch?
...

cmake -S%~dp0 -B%bindir% %opts% ^
  --install-prefix=%install_prefix% ^
  -DMUMPS_openmp:BOOL=%openmp% ^
  -DMUMPS_parallel:BOOL=%parallel% ^
  -DMUMPS_metis:BOOL=%metis% ^
  -DMUMPS_scotch:BOOL=%scotch% ^
  -DMUMPS_parmetis:BOOL=%parmetis%
...

When executing the bat file from the oneAPI terminal, i get the following errors:

Thank you for looking into this!

Best regards,
