You can check that with

apt-cache policy libopenmpi2

There should be a line like

Installed: 2.1.1-9~bionic

The easiest way is to simply follow the install instructions for the binary
packages and install libopm-simulators-bin as you can have installed versions
and still compile and use master without installing.

Then you only need to compile/recompile all opm modules from git master (just
to be sure remove the build directories). No
need to compile the dependencies. I just did that and "mpirun -np 2 flow NORNE_ATW2003" works like a charm.
