[petsc-users] Can not find the header file for OpenMPI

So this is the only issue? Does this dir not exist? If so, you can try the following fix:

https://urldefense.us/v3/__https://gitlab.com/petsc/petsc/-/merge_requests/7545__;!!G_uCfscf7eWS!a7OhWBQn8Zp5RfRnLqjH2JjyNYkp3CksuvTPa8FN5YXKhfigeeaNOYe29DFk4jQywze4XBM6KGVRw1AFXd6_vj0$ 

However if this dir exists [i.e when --with-pkg-dir=DIR is specified and DIR/include exists] - configure will have no way of figuring out that this location is incorrect. And it should cause no harm to include it in compile commands.
