+On Debian and derivates like Ubuntu and Linux Mint the `xorg-dev` meta-package
+pulls in the development packages for all of X11.

@code{.sh}

-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 Debian/Ubuntu and Cygwin MinGW-w64 packages
-have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
-invocation would be:

@subsection compile_generate Generating build files with CMake

 Once you have all necessary dependencies it is time to generate the project
-files or makefiles for your development environment.  CMake needs to know two
-paths for this: the path to the _root_ directory of the GLFW source tree (i.e.
-_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.
-
-@code{.sh}
-mkdir glfw-build
-cd glfw-build
-cmake <glfw-root-dir>
-@endcode
+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
+GLFW section of the variable list, then apply the new value as described above.

 development environment, move on to @ref compile_compile.
