"invalid version 0 on git_proxy_options" thrown when natives are built from source

Hi, I'm currently trying to make a custom build that uses libssh2 instead of exec for SSH, since I don't want OpenSSH windows to spawn as my program makes requests. I changed this flag, then followed through the rest of the compilation steps both for native binaries and lg2s.

I then tried pulling, not on a proxy, using this code:

var fOptions = new FetchOptions ();
fOptions.Prune = UpdaterMod.settings.pruneOld;

var mOptions = new MergeOptions ();
mOptions.CommitOnSuccess = true;
mOptions.FileConflictStrategy = UpdaterMod.settings.onFileConflict;

var sig = new Signature (new Identity (modName, email), DateTimeOffset.Now);

try {
    string logHolder = "";
    Commands.Fetch (repo, remote.Name, refSpecs, fOptions, logHolder);

    if (logHolder.Length > 0)
        LogMsg (logHolder, LogMode.Warn);
}
catch (Exception e) {
    LogMsg ($"Could not fetch data from remote repo: {e.Message}", LogMode.Error);
    return;
}

Expected behavior

The program should attempt to pull without trying to use a proxy.

Actual behavior

The caught exception contains the message in the title.

Other useful information

This issue persists when the flag is switched back to exec

從報告中的 Windows 建置版本上的 Commands.Fetch 呼叫（使用 FetchOptions）開始，然後追蹤 native 建置如何處理 Proxy 選項和版本驗證。使用 custom 和 exec 設定重現 fetch；當不使用 Proxy 的 fetch 不再拋出所報告的無效版本例外時，即表示完成。
