Unknown field addStaticLibrary

Hello!

So small precursor, I basically just discovered Zig and it's build system capabilities and I am still a little mindblown how I missed one of the coolest things. Completely nerdsniped, effectively.

While trying out the `libarchive` build, I discovered this:

I am on Windows 10, and my version of Zig is 0.15.2. I tried with the default target (`x86_64-windows-gnu`, so, mingw) and `x86_64-windows-msvc`. Both of them produce the same error.

Kind regards,
Ingwie. :)
