## Compiling
Q3Rally is compiled using GNU Make (`make`) from a terminal while in the engine directory.
`make ARCH=x86`, `make ARCH=x86_64`, `make ARCH=aarch64` (ARM64/Apple Silicon) specify compiling for a specific architecture instead of the host architecture.
`make ARCH=x86`, `make ARCH=x86_64`, `make ARCH=arm64` (ARM64/Apple Silicon) specify compiling for a specific architecture instead of the host architecture. (Windows ARM64 is unsupported.)
Compiling Linux arm64 from a x86\_64 host requires `CC=aarch64-linux-gnu-gcc`. Compiling for a different architechture than the host on Linux requires setting `SDL_CFLAGS=... SDL_LIBS=...` (see output of pkg-config sdl2 --cflags and --libs) with the paths to a build of SDL2 for that architechture.
If you have commit access and use an SSH key use `git clone git@github.com:Q3Rally-Team/q3rally.git` instead.
