Description of the problem
In recent runs (https://github.com/GenericMappingTools/pygmt/actions/runs/560287188), test_load_libgmt_with_a_bad_library_path fails with GMT dev on Linux and macOS, but pass on Windows, possibly because we merged #702. However, it passed when @weiji14 triggered the dev tests before merging (https://github.com/GenericMappingTools/pygmt/actions/runs/560286224).
It's unclear to me what happens. We can wait for today's scheduled runs and see if it works or not.
See the error messages below:
