I haven't had success in the first attempt. I appreciate it if any Windows user can check my test output: https://github.com/weslleyspereira/lapack/actions/runs/691245251

[langou]

Hi @hokb and Window users in general, we are looking for some Windows users who can help with this attempt of a PR. @weslleyspereira is trying to get CI to test also on Windows machines. (Currently we do not test on Windows machines as part of CI.) @weslleyspereira is able to get the code to compile, but the code does not pass the test suites. Any idea/contribution would be welcome. @langou

Hello!

I found the problem under Win10 + Choco (CMake 3.22.1/mingw GCC 11.2.0/Makefile)
There is a patch that fixes problems with

	 13 - CBLAS-xscblat1 (Failed)
	 16 - CBLAS-xdcblat1 (Failed)
	 19 - CBLAS-xccblat1 (Failed)
	 22 - CBLAS-xzcblat1 (Failed)

tests:

The problem was that if the input is an empty string, i.e. "", CMake INPUT_FILE (stdin) is a directory.

I do not have any problem with LAPACK-xlintstz_ztest_in.

[weslleyspereira]

Thanks for the help, @FulgurIgor. However, there still remain a couple of build issues to be solved.

[weslleyspereira]

I marked this as ready to review. I think we can merge this workflow for Windows even if we do not run the test suite. At least we will be able to guarantee that LAPACK builds on Windows. Moreover, I couldn't reproduce the test failures in my windows machine, so I don't really know what is happening with the Docker image windows-latest from Github.
