 This will build and install mGBA into `/usr/bin` and `/usr/lib`. Dependencies that are installed will be automatically detected, and features that are disabled if the dependencies are not found will be shown after running the `cmake` command after warnings about being unable to find them.

+#### Windows developer building
+
+To build on Windows for development, using MSYS2 is recommended. Follow the installation steps found on their [website](https://msys2.github.io). Make sure you're running the 32-bit version ("MinGW-w64 Win32 Shell") and run this additional command (including the braces) to install the needed dependencies (please note that this involves downloading over 500MiB of packages, so it will take a long time):
+
+	pacman -Sy mingw-w64-i686-{cmake,ffmpeg,gcc,gdb,imagemagick,libzip,pkg-config,qt5,SDL2}
+
+Check out the source code by running this command:
+
+	git clone https://github.com/mgba-emu/mgba.git
+
+Then finally build it by running these commands:
+
+	cd mgba
+	mkdir build
+	cd build
+	cmake .. -G "MSYS Makefiles"
+	make
+
+Please note that this build of mGBA for Windows is not suitable for distribution, due to the scattering of DLLs it needs to run, but is perfect for development.
