Add Windows CI job

[pka]

• I agree to follow the project's code of conduct.
• I added an entry to CHANGES.md if knowledge of this change could be valuable to users.

Test failures are ignored for now, because we have a few failures which are tracked in #219.

Nice work @pka ; here's what I found about the failures:

1. raster::tests::test_create_with_band_type_with_options : we're trying to create /tmp/test.tif which is not valid path in windows. Should use a proper env::temp_dir for platform compat.
2. vector::vector_tests::tests::test_write_features : seems to be from fs::remove_file when the dataset is open. Should remove the file after the dataset is dropped I guess.
3. spatial_ref::tests::auto_identify: the error code is OGRERR_UNSUPPORTED_SRS so I suppose the GDAL installation is outdated / doesn't contain many coordinate systems?

[pka]

Made a separate issue for the test failures: #219

[rmanoka]

Looks good @pka ; we could handle the errors in a separate PR. Should we merge this as is?

[pka]

I don't plan to fix the Windows tests bugs within this PR. When they are fixed, the || true can be removed. It's already useful as it is, since it tests the Windows build.

Just curious, why the -j1?

[pka]

There is a impressive collection of build failures in https://github.com/pka/rust-gdal/actions. cargo build -j1 fixed most of them. My guess is, that bindgen has to be built early, otherwise other crates fail to build.

thread 'main' panicked at 'Unable to find libclang: "the `libclang` shared library at C:\\msys64\\mingw64\\bin\\libclang.dll could not be opened: LoadLibraryExW failed"', C:\Users\runneradmin\.cargo\registry\src\github.com-1ecc6299db9ec823\bindgen-0.59.1\src/lib.rs:2117:31

😕

[pka]

Correction: The main failure -j1 solved was

thread 'main' panicked at 'Could not find `pkg-config` in your path. Please install it before building gdal-sys.', gdal-sys\build.rs:229:17

The libclang.dll could not be opened: LoadLibraryExW failed error was solved with prepending /c/msys64/mingw64/bin to $PATH.

In the meantime, the sdk from gisinternals has GDAL 3.4. So #231 has to be merged first.

[jdroenner]

@pka what is the state of this PR? Is there something missing?

[pka]

It was ready for merge in January 22, but didn't test it again in the meantime. I'll do a rebase and we'll see if the build is still working.

[jdroenner]

great! if all tests are green i will merge it.

[pka]

More failing tests on Windows in the meantime (see #219), but build is working.

[pka]

Incompatible tests are now disabled and CI doesn't ignore failing tests anymore.
