The Windows binaries included here are cross compiled with MinGW under Arch Linux (with packages like mingw-w64-boost, mingw-w64-freetype2-bootstrap, mingw-w64-cmake, mingw-w64-glfw). GLEW remains disabled.
For Android binaries, use F-Droid (https://f-droid.org/repository/browse/fdfilter=pixelflood&fdid=de.lihotzki.pixelflood).
On Linux, just compile it yourself (see README).
