MSVC link error: LNK1181: cannot open input file 'stdc++.lib' when building on Windows 10

[HMaker]

I am trying to build cryptography on Windows 10 from the main branch (version 44.0.0.dev1) but I am getting the following linker error

warning: cargo:rustc-check-cfg requires -Zcheck-cfg=output flag

looks like the linker cannot find stdc++.lib.

What OpenSSL are you attempting to use?

[HMaker]

I am linking against BoringSSL from commit hash e724ef02089bf2bb494203231fc5cb62acc2fad6, same as the one used by cryptography in its tests.

[alex]

#11603 should fix this, can you test and confirm?

[HMaker]

@alex yes it builds now, I think the issue was linking stdc++ in Windows when using the MSVC compiler.

Great
