libvirt-go交叉编译在GOOS=Linux的macos上失败。

Question

我有一个使用利布维特 v7.4.0的项目。

go.mod：

github.com/libvirt/libvirt-go v7.4.0+incompatible // indirect

它在mac和linux上都进行编译，但是在带有GOOS=Linux标志的macos上交叉编译失败了。

$ env GOOS=linux go build -o myapp .

THe libvirt包是一个CGo绑定到本机libvirt平台库。因此，在构建CGO时不可能禁用CGO，反过来也不可能交叉编译，因为这隐式禁用CGO。
