Fix windows CI builds (#1476)
Browse files Browse the repository at this point in the history
* Prevent .pdb files from being generated in windows

* test

* Test another thing

* For tests, find executables for target-specific prusti

* test it

* Try it

* Windows-specific tests

* More

* format

* More reliable finding of executables

* add cfg print for testing

* Try specfiying target in .cargo/config.toml

* Refactor

* Comments and resume normal workflow logic

* Perhaps an even better soln

* Update test.yml

* Put stuff in the right spots

* Revert workflow, update a comment

* test jobs = 1
