/cygdrive/d/HOME/.emacs.d/test/task-3.3.0/Cargo.toml does not exist

          I encountered a similar problem on Cygwin, despite the fact that `Cargo.toml` does exist:

-- Using Corrosion as a subdirectory
error: manifest path `/cygdrive/d/HOME/.emacs.d/test/task-3.3.0/Cargo.toml` does not exist

I'm curious about that .emacs.d in the path -- what is that from? And is the next component /test, related?

Not at all. I just happened to git clone to that path as I am trying to use more Emacs. Before doing this, I have tested at other paths and same error arises too.

Ah, it appears that Cygwin is not supported for Rust -- rust-lang/rust#79854

So the cargo binary you're running is not built for Cygwin, so it has no idea what to do with a /cygdrive path.

I see...

I have tried to fix this by manually set the path of the Cargo.toml in D:\HOME\.emacs.d\test\task-3.3.0\src\taskchampion-cpp\corrosion\cmake\CorrosionGenerator.cmake, but it did not work out. Same result even if I provide a path in Windows format.

Any quick fix for this?

I'm not terribly familiar, as I don't use Windows, but my sense is that MSYS and WSL are the currently-favored technologies for building POSIX applications on the platform. I suspect that attempting to manually fix things in the build process with Cygwin will be a difficult course.
