Configure the compiler:

BUILD_PATH=$HOME/QEMU-bin/
mkdir build && cd build
export CFLAGS="-march=native -mtune=native -O3 -flto=auto"
../configure \                                                                      
 --prefix=$BUILD_PATH \
 --disable-werror

If --prefix errors use absolute path. You should see:

User defined options
    Native files                    : config-meson.cross
                                      C:/msys64/home/user/qemu/configs/meson/windows.txt
    b_pie                           : false
    docs                            : enabled
    plugins                         : true
    prefix                          : C:\msys64\home\user\QEMU-bin
    werror                          : false

Compile with Meson:

meson compile -j $(($(nproc) - 1))
meson install

If --prefix errors use:

meson install DESTDIR=$BUILD_PATH
