Thanks to @wenqing for reporting.

Should fix errors on clang docker builds.

https://github.com/conan-io/cmake-conan/commit/0fb31cd9b99357cb0ecb2b41058daafdef777dc1

Removed jedbrown cmake modules, copied FindPETSc.cmake over.
Check for required Git version.

The file is read by CMake (via new a json parser submodule) and
the web site generator and provides info on required clang and
gcc versions. This info will be expanded in future commits.

Goal is to have a single source of truth for versions infos and
maybe other requirements.

On CMake you access the info via `ogs.`-prefixed variables:

    ${ogs.minimum_version.gcc}

In Hugo you access the info via the new dataFile-shortcode:

    {{< dataFile "versions.minimum_version.gcc" >}}

Should fix runtime issues with mfront dylibs.

When a benchmark uses Python (REQUIREMENTS OGS_USE_PYTHON) and
there is a requirements.txt file in benchmarks project file
directory a Python virtual environment is created and dependencies
are installed during benchmark execution via ctest (inside the
build directory).

The PYTHONPATH environment variable of the benchmark test is set
to the virtual environment to mimic virtual environment activation.

Normally you would use

source .venv/bin/activate

but this is not possible when executing the benchmarks via ctest.

This fixes GUI compilation on Linux.

This is the latest version released today which fixes errors
like in #2687.
