How to add library path in zig build command?

I am trying build android target with ndk.
I found zig build could set libc. But how to add a library path?
First, I try: zig build rundemo -Dtarget=x86_64-linux-android
compiler complain can’t find c/c++ header.
Then, I add libc arg: zig build rundemo -Dtarget=x86_64-linux-android --libc ndk.conf.
then compiler complain can’t find android system library.
Then, I try set --sysroot and --search-prefix, compiler still can’t find android system library.

Now I must do it in build.zig:

module.addLibrary(path);

It worked, but is there a simpler way?

I don’t have the answer, but this thread seems similar and might be helpful: Zig can't find header files for system library
