I am running dealii in Docker container and because of issue to do with
using filesystem under c++17 i have:
*[ 0%] Building CXX object
source/CMakeFiles/rotatingMHD.dir/problem_class.cc.o *
*/home/dealii/rotmhd/source/problem_class.cc: In constructor
‘RMHD::Problem<dim>::Problem(const
RMHD::RunTimeParameters::ProblemBaseParameters&)’:
/home/dealii/rotmhd/source/problem_class.cc:185:13: error:
‘std::filesystem’ has not been declared 185 | if
(!std::filesystem::exists(prm.graphical_output_directory) && |
^~~~~~~~~~ /home/dealii/rotmhd/source/problem_class.cc:190:12:

| ^~~~~~~~~~ make[2]: ***
[source/CMakeFiles/rotatingMHD.dir/build.make:206:
source/CMakeFiles/rotatingMHD.dir/problem_class.cc.o] Error 1*
Does the dealii Docker container support c++17?
