meta-allyourcode

lazy dependencies for zig build. This repository is for writing build.zig configurations for other c/c++ projects

CMake

using the zig build system, this repository bootstraps cmake 3.30.1 without any system cmake or the usual shellscript method. it takes a while and is only tested on x64 linux, but can be used to build your C/C++ dependency libraries.

the package also has a custom CMakeStep that will configure and build and install a cmake project, and providdes a .install(b, name) function to get the artifacts:

zig fetch --save https://github.com/dasimmet/zig-meta-allyourcode/archive/refs/heads/master.tar.gz

build.zig (from example):

pub fn build() void {
  const meta_import = b.lazyImport(@This(), "meta_allyourcode");

  if (meta_import) |meta_allyourcode| {}
  const cmakeStep = meta_allyourcode.addCMakeStep(b, .{
    .target = b.standardTargetOptions(.{}),
    .name = "cmake",
    .source_dir = b.path(""),
      .defines = &.{
          .{ "CMAKE_BUILD_TYPE", if (optimize == .Debug) "Debug" else "Release" },
      },
  });
  cmakeStep.addCmakeDefine();
  const install_step = cmakeStep.install(b, "");
  b.getInstallStep().dependOn(&install_step.step);
}
