-_not_ the `src` subdirectory) and the target path for the generated files and
-compiled binaries.  If these are the same, it is called an in-tree build,
-otherwise it is called an out-of-tree build.
+files or makefiles for your development environment.  CMake needs two paths for
+this:

-One of several advantages of out-of-tree builds is that you can generate files
-and compile for different development environments using a single source tree.
+ - the path to the root directory of the GLFW source tree (not its `src`
+   subdirectory)
+ - the path to the directory where the generated build files and compiled
+   binaries will be placed

-@note This section is about generating the project files or makefiles necessary
-to compile the GLFW library, not about compiling the actual library.
+If these are the same, it is called an in-tree build, otherwise it is called an
+out-of-tree build.
+
+Out-of-tree builds are recommended as they avoid cluttering up the source tree.
+They also allow you to have several build directories for different
+configurations all using the same source tree.
+
+A common pattern when building a single configuration is to have a build
+directory named `build` in the root of the source tree.


-@subsubsection compile_generate_cli Generating files with the CMake command-line tool
+@subsubsection compile_generate_gui Generating files with the CMake GUI

-To make an in-tree build, enter the _root_ directory of the GLFW source tree
-(i.e. _not_ the `src` subdirectory) and run CMake.  The current directory is
-used as target path, while the path provided as an argument is used to find the
-source tree.
+Start the CMake GUI and set the paths to the source and build directories
+described above.  Then press _Configure_ and _Generate_.

-@code{.sh}
-cd <glfw-root-dir>
-cmake .
-@endcode
+If you wish change any CMake variables in the list, press _Configure_ and then
+_Generate_ to have the new values take effect.  The variable list will be
+populated after the first configure step.

-To make an out-of-tree build, make a directory outside of the source tree, enter
-it and run CMake with the (relative or absolute) path to the root of the source
-tree as an argument.

-mkdir glfw-build

+By default GLFW will use X11 on Linux and other Unix-like systems other
+than macOS.  To use Wayland instead, set the `GLFW_USE_WAYLAND` option in the

+for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives

+
+@code{.sh}
+cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=path/to/file
+@endcode
+
+The exact toolchain file to use depends on the prefix used by the MinGW or
+MinGW-w64 binaries on your system.  You can usually see this in the /usr
+directory.  For example, both the Ubuntu and Cygwin MinGW-w64 packages have
+`/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct invocation
+would be:
+
+@code{.sh}

+@endcode

+The path to the toolchain file is relative to the path to the GLFW source tree

+
+When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can
+be enabled if available.
+
+Raw mouse motion is closer to the actual motion of the mouse across a surface.
+It is not affected by the scaling and acceleration applied to the motion of the
+desktop cursor.  That processing is suitable for a cursor while raw motion is
+better for controlling for example a 3D camera.  Because of this, raw mouse
+motion is only provided when the cursor is disabled.

+the OSMesa color and depth buffers.

 There is also a new null backend that uses OSMesa as its native context
 creation API, intended for automated testing.  This backend does not provide
 input.


+@subsection caveats_33 Caveats for version 3.3
+
+@subsubsection joystick_layout_33 Layout of joysticks have changed
+
+The way joystick elements are arranged have changed to match SDL2 in order to
+support SDL_GameControllerDB mappings.  The layout of joysticks may
+change again if required for compatibility with SDL2.  If you need a known and
+stable layout for game controllers, see if you can switch to @ref gamepad.
+
+Existing code that depends on a specific joystick layout will likely have to be
+updated.
+
+
+@subsubsection wait_events_33 No window required to wait for events
+
+The @ref glfwWaitEvents and @ref glfwWaitEventsTimeout functions no longer need
+a window to be created to wait for events.  Before version 3.3 these functions
+would return immediately if there were no user-created windows.  On platforms
+where only windows can receive events, an internal helper window is used.
+
+Existing code that depends on the earlier behavior will likely have to be
+updated.
+
+
+@subsubsection gamma_ramp_size_33 Gamma ramp size of 256 may be rejected
+
+The documentation for versions before 3.3 stated that a gamma ramp size of 256
+would always be accepted.  This was never the case on X11 and could lead to
+artifacts on macOS.  The @ref glfwSetGamma function has been updated to always
+generate a ramp of the correct size.
+
+Existing code that hardcodes a size of 256 should be updated to use the size of
+the current ramp of a monitor when setting a new ramp for that monitor.
+
+
+@subsubsection xinput_deadzone_33 Windows XInput deadzone removed
+
+GLFW no longer applies any deadzone to the input state received from the XInput
+API.  This was never done for any other platform joystick API so this change
+makes the behavior more consistent but you will need to apply your own deadzone
+if desired.
+
+
+@subsubsection x11_clipboard_33 X11 clipboard transfer limits
+
+GLFW now supports reading clipboard text via the `INCR` method, which removes
+the limit on how much text can be read with @ref glfwGetClipboardString.
+However, writing via this method is not yet supported, so you may not be able to
+write a very large string with @ref glfwSetClipboardString even if you read it
+from the clipboard earlier.
+
+The exact size limit for writing to the clipboard is negotiated with each
+receiving application but is at least several tens of kilobytes.  Note that only
+the read limit has changed.  Any string that could be written before still can
+be.
+
+
+@subsubsection x11_linking_33 X11 extension libraries are loaded dynamically
+
+GLFW now loads all X11 extension libraries at initialization.  The only X11
+library you need to link against is `libX11`.  The header files for the
+extension libraries are still required for compilation.
+
+Existing projects and makefiles that link GLFW directly against the extension
+libraries should still build correctly but will add these libraries as load-time
+dependencies.
+
+
+@subsubsection cmake_version_33 CMake 3.0 or later is required
+
+The minimum CMake version has been raised from 2.8.12 to 3.0.  This is only
+a requirement of the GLFW CMake files.  The GLFW source files do not depend on
+CMake.
+
+
+@subsubsection caveat_fbtransparency_33 Framebuffer transparency requires DWM transparency
+
+GLFW no longer supports framebuffer transparency enabled via @ref
+GLFW_TRANSPARENT_FRAMEBUFFER on Windows 7 if DWM transparency is off
+(the Transparency setting under Personalization > Window Color).
+
+
+@subsubsection emptyevents_33 Empty events on X11 no longer roundtrip to server
+
+Starting with GLFW 3.3.7, events posted with @ref glfwPostEmptyEvent now use a separate
+unnamed pipe instead of sending an X11 client event to the helper window.
+
+
+@subsection deprecations_33 Deprecations in version 3.3
+
+@subsubsection charmods_callback_33 Character with modifiers callback
+
+The character with modifiers callback set with @ref glfwSetCharModsCallback has
+been deprecated and should if possible not be used.
+
+Existing code should still work but further bug fixes will likely not be made.
+The callback will be removed in the next major version.
+
+
+@subsubsection clipboard_window_33 Window parameter to clipboard functions
+
+The window parameter of the clipboard functions @ref glfwGetClipboardString and
+@ref glfwSetClipboardString has been deprecated and is no longer used on any
+platform.  On platforms where the clipboard must be owned by a specific window,
+an internal helper window is used.
+
+Existing code should still work unless it depends on a specific window owning
+the clipboard.  New code may pass `NULL` as the window argument.  The parameter
+will be removed in a future release.
+
+
+@subsection removals_33 Removals in 3.3
+
+@subsubsection macos_options_33 macOS specific CMake options and macros
+
+The `GLFW_USE_RETINA`, `GLFW_USE_CHDIR` and `GLFW_USE_MENUBAR` CMake options and
+the `_GLFW_USE_RETINA`, `_GLFW_USE_CHDIR` and `_GLFW_USE_MENUBAR` compile-time
+macros have been removed.
+
+These options and macros are replaced by the window hint
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
+and the init hints
+[GLFW_COCOA_CHDIR_RESOURCES](@ref GLFW_COCOA_CHDIR_RESOURCES_hint) and
+[GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint).
+
+Existing projects and makefiles that set these options or define these macros
+during compilation of GLFW will still build but it will have no effect and the
+default behaviors will be used.
+
+
+@subsubsection vulkan_sdk_33 LunarG Vulkan SDK dependency
+
+The GLFW test programs that previously depended on the LunarG Vulkan SDK now
+instead uses a Vulkan loader generated by
+[glad2](https://github.com/Dav1dde/glad).  This means the GLFW CMake files no
+longer look for the Vulkan SDK.
+
+Existing CMake projects that depended on the Vulkan SDK cache variables from
+GLFW will need to call `find_package(Vulkan)` themselves.  CMake 3.7 and later
+already comes with a
+[Vulkan find module](https://cmake.org/cmake/help/latest/module/FindVulkan.html)
+similar to the one GLFW previously included.
+
+
+@subsubsection lib_suffix_33 CMake option LIB_SUFFIX
+
+The `LIB_SUFFIX` CMake option has been removed.  GLFW now uses the
+GNUInstallDirs CMake package to handle platform specific details like the
+library directory suffix and the `LIB_SUFFIX` CMake option has been removed.
+
+Existing projects and makefiles that set the `LIB_SUFFIX` option will use the
+suffix chosen by the GNUInstallDirs package and the option will be ignored.
+
+
+@subsubsection wl_shell_33 Support for the wl_shell protocol
+
+Support for the wl_shell protocol has been removed and GLFW now only supports
+the XDG-Shell protocol.  If your Wayland compositor does not support XDG-Shell
+then GLFW will fail to initialize.
+
+
+@subsubsection mir_removed_33 Mir support
+
+The experimental Mir support has been completely removed as the Mir project has
+implemented support for the Wayland protocol and is recommending that
+applications use that instead.
+
+Existing projects and makefiles that select Mir when compiling GLFW will fail.
+Use Wayland or X11 instead.

+@subsection window_transparency Window transparency
+
+GLFW supports two kinds of transparency for windows; framebuffer transparency
+and whole window transparency.  A single window may not use both methods.  The
+results of doing this are undefined.
+
+Both methods require the platform to support it and not every version of every
+platform GLFW supports does this, so there are mechanisms to check whether the
+window really is transparent.
+
+Window framebuffers can be made transparent on a per-pixel per-frame basis with

+window hint.
+
+@code
+glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE);
+@endcode
+
+If supported by the system, the window content area will be composited with the
+background using the framebuffer per-pixel alpha channel.  This requires desktop
+compositing to be enabled on the system.  It does not affect window decorations.

+with the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_attrib)
+window attribute.
+
+@code

+The opacity of the whole window, including any decorations, can be set with @ref
+glfwSetWindowOpacity.
+
+@code
+glfwSetWindowOpacity(window, 0.5f);
+@endcode
+
+The opacity (or alpha) value is a positive finite number between zero and one,
+where 0 (zero) is fully transparent and 1 (one) is fully opaque.  The initial
