bug#25327: cargo build-system should be able to filter out target.cfg(windows) dependencies

[ng0]

The cargo build-system should be able to filter out Windows
dependencies.
Ignore blocks with this in Cargo.toml files:
[target.'cfg(windows)'.dependencies]

until the next [ ] starts.

I also found that most *32-sys packages (currently ALL *32-sys
I've seen) are windows specific.
As the build system is simple enough to not complain, you just
have to learn about this while doing the work.

This bug is really old and the story about cargo has a bit evolved.  Is
it still relevant with the recent additions?

If no, feel free to close it.  And without more comment, I will close it
after the usual 2 weeks delay.


All the best,

I just checked this with sequoia 0.20.0: The package "winapi" is still 
downloaded and compiled - even if obviously not used sicne on Linux.

Should the remove of this “winapi” happen at the build-system level or
at the package per package level?

Other said, are the Windows dependencies normalized by Cargo?

     Hi zimoun,  

  
I think that the configuration phase will fail even if conditional compilation dependencies are missing.    It’s worth a shot though!
