DOCS/compile-windows.md: update with meson instructions

No need to encourage waf here.

 Compiling for Windows is supported with MinGW-w64. This can be used to produce
 both 32-bit and 64-bit executables, and it works for building on Windows and
 cross-compiling from Linux and Cygwin. MinGW-w64 is available from:
-http://mingw-w64.sourceforge.net.
+https://www.mingw-w64.org/
 
 While building a complete MinGW-w64 toolchain yourself is possible, there are a
 few build environments and scripts to help ease the process, such as MSYS2 and
 MXE. Note that MinGW environments included in Linux distributions are often
 broken, outdated and useless, and usually don't use MinGW-w64.
 
-**Warning**: the original MinGW (http://www.mingw.org) is unsupported.

 Cross-compilation
 =================
 
-When cross-compiling, you have to run mpv's configure with these arguments:
+When cross-compiling, it is recommended to use a meson crossfile to setup
+the cross compiling environment. A minimal example is included below:
 
-```bash
-DEST_OS=win32 TARGET=i686-w64-mingw32 ./waf configure
+```ini
+[binaries]
+c = 'x86_64-w64-mingw32-gcc'

 [MXE](https://mxe.cc) makes it very easy to bootstrap a complete MingGW-w64
 environment from a Linux machine. See a working example below.
