Kwant is not built with Mumps support when using nonstandard shells
Steps to reproduce
Execute the following in the fish
shell on a freshly-cloned Kwant:
~> eval /path/to/conda shell.fish hook | source
~> conda env create -f docker/kwant-latest.yml
~> conda activate kwant-latest
~> rm -rf build
~> python setup.py build
You should see that Kwant is not built with Mumps support, even though the relevant libraries are installed in kwant-latest
Compare this with the same steps executed in bash
:
$ /path/to/conda shell.bash hook | source
$ conda activate kwant-latest
$ rm -rf build
$ python setup.py build
