Intel OneAPI build

[fsimonis]

I managed to build and run preCICE without PETSc using the Intel compiler, Intel MPI and Intel python in the docker container.

Used:

docker run --rm --shm-size=512m -it intel/oneapi-hpckit:devel-ubuntu20.04

Not sure if increasing shared memory is required after the updates though.

Required as the container doesn't contain the newest versions.

apt update && apt upgrade

Then

apt install libboost-dev-all libboost-filesystem-dev libboost-test-dev libboost-porgram-options-dev libeigen3-dev

LibXml2 is part of the intel python installation, but not detected by CMake.

I was able to build with:

cmake -DPRECICE_PETScMapping=Off -DLibXml2_ROOT=/opt/intel/oneapi/intelpython/python3.9/ ..

Setting CMAKE_PREFIX_PATH somehow doesn't work.

One has to disable com.mpiports. I am not sure why m2n.mpiports works flawlessly.

ctest --repeat until-fail:20 -E com.mpiports
