zig build support

[star-tek-mb]

Hello.

Zig is a general-purpose programming language and toolchain for maintaining robust, optimal and reusable software.

Zig can leverage C source code base and recently got support for package manager (master branch). So it would be easy to use pcre2 in Zig projects.

Build standalone library with:

zig build

Or use it in your project:

Specify dependency in manifest build.zig.zon:

.{
    .name = "example",
    .version = "0.0.0",

    .dependencies = .{
        .pcre2 = .{
            .url = "https://github.com/PCRE2Project/pcre2/archive/fa35393d7935f7ef2833bf89d16d49a05c17923b.tar.gz",
            .hash = "1220cd78969639ad750886231c71cdb991459792ac2187ad57552aab9df97a8ba98c",
        },
    },
}

Hash and commit will be different.

In build.zig link pcre2 to your executable.

const pcre2_dep = b.dependency("pcre2", .{
    .target = target,
    .optimize = optimize,
});
exe.linkLibrary(pcre2_dep.artifact("pcre2"));

There is a precedent here in the form of the .bazel files in the repo. I do not mind adding your zig file. However, would you want it included in the tarballs for PCRE2 releases? (I see that the Bazel files are not so included.)

I don't mind. But it is not necessary for now. Most of the time, sha commit from git is fetched. And zig package manager is MVP for now. I will try to maintain it in time. Thanks!
