Publish compiled wheels for Windows

[scottgigante]

Thanks for publishing precompiled wheels for Linux and MacOS. Would it be possible to publish wheels for Windows as well?

Thanks!

Since we understand Windows is an important OS for NGT, we are considering that. So far, we have no plan for that.

Thank you for the update!

fwiw, I tried compiling NGT on Windows with GitHub Actions. I'm not very good at C++, but wanted to report my findings for others.

The following errors occurred:

1. error C3646: '_mutex': unknown override specifier
2. error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
3. fatal error C1083: Cannot open include file: 'sys/time.h'
4. fatal error C1083: Cannot open include file: 'unistd.h'
5. fatal error C1083: Cannot open include file: 'pthread.h'

From what I can tell, 1 and 2 are likely smaller changes that will be compatible with Unix.

For 3, 4, and 5, there are some suggested approaches on Stack Overflow.

• sys/time.h
• unistd.h
• pthread.h

Overall, I imagine this would take some time.

(had to set -D UNIX=ON for it to build the library)

Windows support would be great! I'm trying to use NGT on a client-side app, so lacking Windows support is really a bummer.
