+# Typical usage:
+#    1) install cross compiler: `sudo pacman -S mingw32-gcc`
+#    2) cp cmake/Toolchain-Arch-mingw32.cmake.sample ~/Toolchain-Arch-mingw32.cmake
+#    3) tweak toolchain values as needed
+#    4) cd build
+#    5) cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-Arch-mingw32.cmake ..
+
+# name of the target OS on which the built artifacts will run
+# and the toolchain prefix
+set(CMAKE_SYSTEM_NAME Windows)
