$ sudo apt install xorg-dev libopengl-dev ibgl1-mesa-glx libgl1-mesa-dev

and for glfw3

$ sudo apt install libglfw3 libglfw3-dev

and for sdl2

$ sudo apt install libsdl2-dev

Build

First clone this project,

git clone --recursive https://github.com/dinau/imguin

Sample program is here, examples.
For instance, glfw_opengl3.nim:
```
cd imguin/examples/glfw_opengl3
make
```

Update to latest Dear ImGui and CImGui

Prerequisite

Git installed.
Windows10 or later
Clang/LLVM refer to Futhark installation.
```
nimble install futhark 
```

Linux Debian 11 Bullseye

sudo apt install  libclang-dev
nimble install --passL:"-L/usr/lib/llvm-11/lib" futhark

Important Notice: Confirm Futhark version is v0.9.1 or later.

nimble dump futhark

Update ImGui/CImGui

Update to latest definition files uisng Futhark,
```
pwd
imguin
cd src/updater
make
```
ImGui/CImGui version is v1.89.5 at this time. (2023/05)
Update/Downgrade to the version that specified tag of CImGui for example,
```
pwd
updater
make CIMGUI=1.86
or
make VER=1.86
```

Examples notice

examples/sdl2_opengl3
1. If you are on Windows OS 32bit, you should get SDL2.dll for instance from release-2.26.4.
  1. Unzip SDL2-2.26.4-win32-x86.zip
  2. Copy SDL2.dll to examples/sdl2_opengl3 folder.
2. On Windows OS, it needs dev tool to compile SDL2 app,
  SDL2-devel-2.26.4-mingw.zip
  for instance "SDL.h","-lSDL2.dll" etc
  and change src/imguin/sdl2_opengl.nim
```
{.passC:"-Id:/msys32/mingw32/include/SDL2".}
{.passL:"-Ld:/msys32/mingw32/lib -lSDL2.dll".}
```
  you need to properly change the above folder name depending on your settings.
  See src/imguin/sdl2_opengl.nim

TODO

Easier compilation for SDL2 app.
Whether can it do nimble install imguin ?
Whether can it use cimgui.dll ? (Now it can only be static link)
~~Add Font Awesome (Icon Font) demo.~~ Done (2023/04).
~~Can it compile with MSVC (--cc:vcc) ?~~ Done. Except SDL2 demo. (2023/03)
~~Can it compile with Clang (--cc:clang) ?~~ Done. (2023/03)
~~Add SDL2 example.~~ Done. examples/sdl2_opengl3 (2023/03)

First step is done. (2023/03)
