Binding to core 0 is default behaviour of mpirun(1):

Please note that mpirun automatically binds processes as of the start of the v1.8 series. Three binding patterns are used in the absence of any further directives:

Bind to core: when the number of processes is <= 2
Bind to socket: when the number of processes is > 2
Bind to none: when oversubscribed

Removed hard-coded build-time venv.

This can happen if you have the ogs-wheel installed but are running a local ogs binary. In this case use `import OpenGeoSys` or uninstall the wheel.

Allows co-existance with ogstools python package in build dir virtual environment.

Requires to uninstall ogs wheel in venv and to set the PYTHONPATH (both handled by CMake and .envrc-file used by the direnv-tool).

CLI flags without additional value can now be given with e.g.:

cli.GMSH2OGS(gmsh2_physical_id=True) # or gmsh2_physical_id=None

cli.GMSH2OGS(gmsh2_physical_id=False) # disables the flag.

- pytest is added to requirements-dev.txt
- 'pytest' ctest is added

[T] Disable pytest on sanitizer build.

Tests have to write to different output files when running concurrently.

- with option --copy-material_ids instead of --set-material-id
- without options --copy-material_ids and --set-material-id
- failing test where contradicting options are set

Should fix pytest issue.

Remove unused boost/... headers.

This tool parses vtkfdiff output from OGS log files and outputs a summary
of error norms in a format that can be copy-pasted into the
<test_definition> section of the prj file.

The Simulation instance needs to be alive upon Python exception
handling, otherwise e.what() will lead to a segfault.
Why? → Because Simulation "owns" the Python interpreter.
