- zig-x86_64-linux-0.17.0.tar.xz
- zig-0.18.0-dev.1+a6c6412a8: Windows
- zig-0.16.0 for Raylib examples
Windows11
- MSys2/MinGW basic commands (make, rm, cp, strip ...)
```
pacman -S make 
```

Linux OS (Ubuntu / Debian families)

 sudo apt install lib{opengl-dev,gl1-mesa-dev,glfw3,glfw3-dev,xcursor-dev,xinerama-dev,xi-dev} git make

SDL3
install SDL3 manually

Build and run

git clone https://github.com/dinau/imguinz
cd imguinz/examples/glfw_opengl3              # cd one of examples
make run                                      # or  zig build --release=fast run

glfw_webgl_wasm

Install emscripten

Specify emsdk 6.0.9²

emsdk install  6.0.9 
emsdk activate 6.0.9

for WebGL

embuilder build contrib.glfw3    # Rerun after emsdk updated

Go to examples/glfw_webgl_wasm folder
Run emsdk_env.bat(Windows) or emsdk_env.sh(Linux) in your console

[!IMPORTANT]
```
emsdk_env.bat     # Run this once in every new console
```
Build WebGL/Wsam example
```
make run
```
See ./Makefile
You can also build native application
```
make app
```

glfw_wgpu_wasm

WebGPU wasm example

Basically same as WebGL example

for WebGPU

embuilder build emdawnwebgpu    # Rerun after emsdk updated

emsdk_env.bat  # Run this once in every new console

make run

This example can't build native applicaton.

Start your project

Use zig-0.16.0 or later

Zig fetch imguinz

mkdir myapp
cd myapp
zig init

zig fetch --save git+https://github.com/dinau/imguinz

Add dependencies to build.zig
Please insert the following lines above b.installArtifact(exe);.

const imguinz = b.dependency("imguinz", .{});
const dependencies = .{
    "appimgui",      // Simple app framework
    "imspinner",     // ImSpinner
    "imknobs",       // ImKnobs
    "imtoggle",      // ImToggle
 // "another_lib",
};
inline for (dependencies) |dep_name| {
    const dep = imguinz.builder.dependency(dep_name, .{
        .target = target, 
        .optimize = optimize, 
    });
    exe.root_module.addImport(dep_name, dep.module(dep_name));
}
//exe.subsystem = if (builtin.zig_version.minor >= 17) .windows else .windows;

You can set dependencies (additional libraries), see imguinz/build.zig.zon
