@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} @code{.sh}
cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> . sudo apt install xorg-dev
@endcode @endcode

One of several advantages of out-of-tree builds is that you can generate files - the path to the root directory of the GLFW source tree (not its `src`

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).
