Fatal error: 'stdio.h' file not found in compiling c file

Question

I downloaded libwsclient c library as git clone https://github.com/payden/libwsclient.git Inside the generated folder libwsclient I wrote build.zig as:

const Builder = @import("std").build.Builder;

pub fn build(b: *Builder) void {
    const target = b.standardTargetOptions(.{});
    const mode = b.standardOptimizeOption(.{});
    const lib = b.addStaticLibrary(.{
        .name = "wsclientlib",
        .root_source_file = .{ .path = "wsclient.c" },
        .target = target,
        .optimize = mode,
    });
    b.installArtifact(lib);
}

And tried to build the library as zig build but I got the below:

[hasany@hasan-20tes1n300 libwsclient]$ zig build
zig build-lib wsclientlib Debug native: error: error(compilation): clang failed with stderr: /home/hasany/Documents/zig-tutorial/chrome-development-tool/libwsclient/wsclient.c:1:10: fatal error: 'stdio.h' file not found

fatal error: 'stdio.h' file not found

This is a hint that you need to tell Zig to link libc.

You can do this in build.zig by adding

lib.linkLibC();

This is equivalent to adding the -lc argument to the zig build-lib command.
