@subsubsection compile_deps_mingw_cross Dependencies for MinGW or MinGW-w64 cross-compilation
 Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
 example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
 for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
 like Ubuntu have the `mingw-w64` package for both.
 GLFW has CMake toolchain files in the `CMake/` directory that set up
 cross-compilation of Windows binaries.  To use these files you add an option
 when running `cmake` to generate the project files or makefiles:
@code{.sh}
-cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
+sudo apt install xorg-dev
@endcode

 have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct

 the `libwayland-dev` package, which contains all Wayland headers and pulls in

 packages.
 Once you have installed the necessary packages, move on to @ref
 compile_generate.
@subsection compile_deps_osmesa Dependencies for Linux and OSMesa
 To compile GLFW for OSMesa, you need to install the OSMesa library and header
 packages.  For example, on Ubuntu and other distributions based on Debian
 GNU/Linux, you need to install the `libosmesa6-dev` package.  The OSMesa library
 is required at runtime for context creation and is loaded on demand.
 Once you have installed the necessary packages, move on to @ref
 compile_generate.

 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.

@section compile_mingw_cross Cross-compilation with CMake and MinGW
 Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
 example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
 for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
 like Ubuntu have the `mingw-w64` package for both.
 GLFW has CMake toolchain files in the `CMake` subdirectory that set up
 cross-compilation of Windows binaries.  To use these files you set the
 `CMAKE_TOOLCHAIN_FILE` CMake variable with the `-D` flag add an option when
 configuring and generating the build files.
@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}
 cmake -S path/to/glfw -B path/to/build -D CMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake
@endcode
 The path to the toolchain file is relative to the path to the GLFW source tree
 passed to the `-S` flag, not to the current directory.
 For more details see the
 [CMake toolchain guide](https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html).
