Subject: [PATCH] refactor: window (#34)

* build: add SDL3 dependency

* refactor(window): migrate from GLFW to SDL3 for window and input

* refactor: remove unused GLFW includes and commented-out code

* refactor(input): use relative mouse motion and simplify camera mouse update

* refactor(event-handling): guard input events with imgui state

Move mouse enable/disable logic into set_imgui_enabled and check imgui_enable before forwarding non-ImGui events to handlers. This prevents duplicate processing and ensures proper mouse state when toggling ImGui.

* fix(camera): reset camera on resize events and fix input handling on imgui toggle

- Add Camera::player() accessor.
- Handle WindowResizeEvent and FrameBufferResizeEvent to reset camera.
- Fix escape key handling to disable mouse before toggling imgui.
- Fix left alt handling to toggle mouse state correctly.
- Reset player key status when toggling imgui.

* fix(client_world): add direct exit flag to break connection error loop

* refactor(debug): add d_rep template and remove widget ID

* feat(debug_collector): add video driver display to debug UI

* fix: invert debug flag logic and rename to no_debug

The previous 'debug_on' field was never set to true by default, causing
debug mode to never be enabled. Now renamed to 'no_debug' and the
renderer initializes with debug enabled unless the --no-debug flag is
given.

* feat(window): add video driver selection via config and --video-driver argument

* ci: add vcpkg cache

* fix: mscv cpp version show

* fix: context delete too early

* fix: ci build fail

* fix: opengl resource delete error

* fix: add // NOLINT for NvOptimusEnablement and AmdPowerXpressRequestHighPerformance

* fix: windows ime fail on fullscreen

* feat(ui): update text input area on field changes and window resize

* fix(ui): initialize m_app pointer to nullptr

* feat(window): add exclusive fullscreen support with WM detection

* refactor: simplify WM detection and exclusive fullscreen default

Removed WindowManager enum; detect_wm() now returns string directly.
Default exclusive fullscreen based on platform (true on Linux).
Added WM info to debug overlay.

* feat: add Alt key to close ImGui; clarify debug log

* refactor(dev-panel): remove direct settings UI from settings tab

-// dear imgui: Platform Backend for GLFW
-// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
-// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
-// (Requires: GLFW 3.0+. Prefer GLFW 3.3+/3.4+ for full feature support.)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
-//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors) with GLFW 3.1+. Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-//  [X] Multiple Dear ImGui contexts support.
-// Missing features or Issues:
-//  [ ] Platform: Touch events are only correctly identified as Touch on Windows. This create issues with some interactions. GLFW doesn't provide a way to identify touch inputs from mouse inputs, we cannot call io.AddMouseSourceEvent() to identify the source. We provide a Windows-specific workaround.
-//  [ ] Platform: Missing ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress cursors.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// About Emscripten support:
-// - Emscripten provides its own GLFW (3.2.1) implementation (syntax: "-sUSE_GLFW=3"), but Joystick is broken and several features are not supported (multiple windows, clipboard, timer, etc.)
-// - A third-party Emscripten GLFW (3.4.0) implementation (syntax: "--use-port=contrib.glfw3") fixes the Joystick issue and implements all relevant features for the browser.
-// See https://github.com/pongasoft/emscripten-glfw/blob/master/docs/Comparison.md for details.
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2026-03-25: Mouse cursor is properly restored if changed by user app/code while using glfwSetInputMode(..., GLFW_CURSOR_DISABLED) or ImGuiConfigFlags_NoMouseCursorChange. Amend change from 2025-12-10.
-//  2026-02-10: Try to set IMGUI_IMPL_GLFW_DISABLE_X11 / IMGUI_IMPL_GLFW_DISABLE_WAYLAND automatically if corresponding headers are not accessible. (#9225)
-//  2025-12-12: Added IMGUI_IMPL_GLFW_DISABLE_X11 / IMGUI_IMPL_GLFW_DISABLE_WAYLAND to forcefully disable either.
-//  2025-12-10: Avoid repeated glfwSetCursor()/glfwSetInputMode() calls when unnecessary. Lowers overhead for very high framerates (e.g. 10k+ FPS).
-//  2025-11-06: Lower minimum requirement to GLFW 3.0. Though a recent version e.g GLFW 3.4 is highly recommended.
-//  2025-09-18: Call platform_io.ClearPlatformHandlers() on shutdown.
-//  2025-09-15: Content Scales are always reported as 1.0 on Wayland. FramebufferScale are always reported as 1.0 on X11. (#8920, #8921)
-//  2025-07-08: Made ImGui_ImplGlfw_GetContentScaleForWindow(), ImGui_ImplGlfw_GetContentScaleForMonitor() helpers return 1.0f on Emscripten and Android platforms, matching macOS logic. (#8742, #8733)

-//  2024-08-22: Moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
-//               - io.GetClipboardTextFn    -> platform_io.Platform_GetClipboardTextFn
-//               - io.SetClipboardTextFn    -> platform_io.Platform_SetClipboardTextFn
-//               - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn
-//  2024-07-31: Added ImGui_ImplGlfw_Sleep() helper function for usage by our examples app, since GLFW doesn't provide one.
-//  2024-07-08: *BREAKING* Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback to ImGui_ImplGlfw_InstallEmscriptenCallbacks(), added GLFWWindow* parameter.
-//  2024-07-08: Emscripten: Added support for GLFW3 contrib port (GLFW 3.4.0 features + bug fixes): to enable, replace -sUSE_GLFW=3 with --use-port=contrib.glfw3 (requires emscripten 3.1.59+) (https://github.com/pongasoft/emscripten-glfw)
-//  2024-07-02: Emscripten: Added io.PlatformOpenInShellFn() handler for Emscripten versions.

-//  2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
-//  2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
-//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)

-//  2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
-//  2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
-//  2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
-//  2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
-//  2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
-//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-//  2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-//  2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
-//  2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
-//  2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.

-//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-//  2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
-//  2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
-//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-//  2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
-//  2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
-//  2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
-//  2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
-//  2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
-//  2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-//  2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
-//  2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
-//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-//  2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
-//  2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
-//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-//  2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
-//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-//  2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-//  2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
-//  2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-//  2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
-//  2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
-//  2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

-// dear imgui: Platform Backend for GLFW
-// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
-// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
-// (Requires: GLFW 3.0+. Prefer GLFW 3.3+/3.4+ for full feature support.)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
-//  [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors) with GLFW 3.1+. Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-//  [X] Multiple Dear ImGui contexts support.
-// Missing features or Issues:
-//  [ ] Platform: Touch events are only correctly identified as Touch on Windows. This create issues with some interactions. GLFW doesn't provide a way to identify touch inputs from mouse inputs, we cannot call io.AddMouseSourceEvent() to identify the source. We provide a Windows-specific workaround.
-//  [ ] Platform: Missing ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress cursors.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

+// dear imgui: Platform Backend for SDL3
+// This needs to be used along with a Renderer (e.g. SDL_GPU, DirectX11, OpenGL3, Vulkan..)
+// (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
+
+// Implemented features:
+//  [X] Platform: Clipboard support.
+//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
+//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values are obsolete since 1.87 and not supported since 1.91.5]
+//  [X] Platform: Gamepad support.
+//  [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+//  [X] Platform: IME support.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2026-02-13: Inputs: systems other than X11 are back to starting mouse capture on mouse down (reverts 2025-02-26 change). Only X11 requires waiting for a drag by default (not ideal, but a better default for X11 users). Added ImGui_ImplSDL3_SetMouseCaptureMode() for X11 debugger users. (#3650, #6410, #9235)
+//  2026-01-15: Changed GetClipboardText() handler to return nullptr on error aka clipboard contents is not text. Consistent with other backends. (#9168)
+//  2025-11-05: Fixed an issue with missing characters events when an already active text field changes viewports. (#9054)
+//  2025-10-22: Fixed Platform_OpenInShellFn() return value (unused in core).
+//  2025-09-24: Skip using the SDL_GetGlobalMouseState() state when one of our window is hovered, as the SDL_EVENT_MOUSE_MOTION data is reliable. Fix macOS notch mouse coordinates issue in fullscreen mode + better perf on X11. (#7919, #7786)
+//  2025-09-18: Call platform_io.ClearPlatformHandlers() on shutdown.
+//  2025-09-15: Use SDL_GetWindowDisplayScale() on Mac to output DisplayFrameBufferScale. The function is more reliable during resolution changes e.g. going fullscreen. (#8703, #4414)
+//  2025-06-27: IME: avoid calling SDL_StartTextInput() again if already active. (#8727)
+//  2025-04-22: IME: honor ImGuiPlatformImeData->WantTextInput as an alternative way to call SDL_StartTextInput(), without IME being necessarily visible.
+//  2025-04-09: Don't attempt to call SDL_CaptureMouse() on drivers where we don't call SDL_GetGlobalMouseState(). (#8561)
+//  2025-03-30: Update for SDL3 api changes: Revert SDL_GetClipboardText() memory ownership change. (#8530, #7801)
+//  2025-03-21: Fill gamepad inputs and set ImGuiBackendFlags_HasGamepad regardless of ImGuiConfigFlags_NavEnableGamepad being set.
+//  2025-03-10: When dealing with OEM keys, use scancodes instead of translated keycodes to choose ImGuiKey values. (#7136, #7201, #7206, #7306, #7670, #7672, #8468)
+//  2025-02-26: Only start SDL_CaptureMouse() when mouse is being dragged, to mitigate issues with e.g. Linux debuggers not claiming capture back. (#6410, #3650)
+//  2025-02-24: Avoid calling SDL_GetGlobalMouseState() when mouse is in relative mode.
+//  2025-02-18: Added ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress mouse cursor support.
+//  2025-02-10: Using SDL_OpenURL() in platform_io.Platform_OpenInShellFn handler.
+//  2025-01-20: Made ImGui_ImplSDL3_SetGamepadMode(ImGui_ImplSDL3_GamepadMode_Manual) accept an empty array.
+//  2024-10-24: Emscripten: SDL_EVENT_MOUSE_WHEEL event doesn't require dividing by 100.0f on Emscripten.
+//  2024-09-03: Update for SDL3 api changes: SDL_GetGamepads() memory ownership revert. (#7918, #7898, #7807)
+//  2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
+//               - io.GetClipboardTextFn    -> platform_io.Platform_GetClipboardTextFn
+//               - io.SetClipboardTextFn    -> platform_io.Platform_SetClipboardTextFn
+//               - io.PlatformSetImeDataFn  -> platform_io.Platform_SetImeDataFn
+//  2024-08-19: Storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*.
+//  2024-08-19: ImGui_ImplSDL3_ProcessEvent() now ignores events intended for other SDL windows. (#7853)
+//  2024-07-22: Update for SDL3 api changes: SDL_GetGamepads() memory ownership change. (#7807)
+//  2024-07-18: Update for SDL3 api changes: SDL_GetClipboardText() memory ownership change. (#7801)
+//  2024-07-15: Update for SDL3 api changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794)
+//  2024-07-02: Update for SDL3 api changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762).
+//  2024-07-01: Update for SDL3 api changes: SDL_SetTextInputRect() changed to SDL_SetTextInputArea().
+//  2024-06-26: Update for SDL3 api changes: SDL_StartTextInput()/SDL_StopTextInput()/SDL_SetTextInputRect() functions signatures.
+//  2024-06-24: Update for SDL3 api changes: SDL_EVENT_KEY_DOWN/SDL_EVENT_KEY_UP contents.
+//  2024-06-03; Update for SDL3 api changes: SDL_SYSTEM_CURSOR_ renames.
+//  2024-05-15: Update for SDL3 api changes: SDLK_ renames.
+//  2024-04-15: Inputs: Re-enable calling SDL_StartTextInput()/SDL_StopTextInput() as SDL3 no longer enables it by default and should play nicer with IME.
+//  2024-02-13: Inputs: Fixed gamepad support. Handle gamepad disconnection. Added ImGui_ImplSDL3_SetGamepadMode().
+//  2023-11-13: Updated for recent SDL3 API changes.
+//  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
+//  2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
+//  2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
+//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
+//  2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
+//  2023-02-07: Forked "imgui_impl_sdl2" into "imgui_impl_sdl3". Removed version checks for old feature. Refer to imgui_impl_sdl2.cpp for older changelog.

+// dear imgui: Platform Backend for SDL3
+// This needs to be used along with a Renderer (e.g. SDL_GPU, DirectX11, OpenGL3, Vulkan..)
+// (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
+
+// Implemented features:
+//  [X] Platform: Clipboard support.
+//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
+//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values are obsolete since 1.87 and not supported since 1.91.5]
+//  [X] Platform: Gamepad support.
+//  [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+//  [X] Platform: IME support.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
+// Learn about Dear ImGui:
+// - FAQ                  https://dearimgui.com/faq
+// - Getting Started      https://dearimgui.com/getting-started
