Pre-build requirements

1. Install dependencies: cat requirements.txt |xargs sudo apt install
2. Get compilers for arm64 and amd64. If you're only gonna build only for your native system, at least you need to setup the mock compilers.

# ==== Build ARM (from x86-64 native) ====
# Get compilers for aarch64
sudo dpkg --add-architecture arm64 && sudo apt update
sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
# IMPORTANT! Link mock compiler to native x86-64 compiler
sudo ln -s /usr/bin/gcc /usr/bin/x86-64-linux-gnu-gcc
sudo ln -s /usr/bin/g++ /usr/bin/x86-64-linux-gnu-g++

# ==== Build x86-64 (from ARM native) ====
# Get compilers for x86-64
sudo dpkg --add-architecture amd64 && sudo apt update
sudo apt install gcc-x86-64-linux-gnu g++-x86-64-linux-gnu
# IMPORTANT! Link mock compiler to native aarch64 compiler
sudo ln -s /usr/bin/gcc /usr/bin/aarch64-linux-gnu-gcc
sudo ln -s /usr/bin/g++ /usr/bin/aarch64-linux-gnu-g++

Note: The previous commands are for debian, you shall adecuate it to your distro requirements.

2. Bake assets before building (or when they change): ./bake_assets.sh

3. Run ./make_libs.sh all this will automatically download and build all the required static libs like SDL, box2d, etc.
   This will take a while, go for a coffee.

Build and Run

1. You can use vscode extension for CMake for configure/build/pack. (This is what I use because it's comfortable).
2. If you want to build from console, select a preset from CMakePresets.json as follows:

cmake --preset linux-release-x86_64      # Select preset
cmake --build build/linux-x86_64/release # Build it
cpack --preset linux-release-x86_64      # Pack it for distribution

NOTE: For windows, you can test with find dist -name sandsaga.exe |xargs wine.

System requirements (minimum)

The following table repesents the worst hardware where the game has been tested to work at ~60 FPS stable.

	Windows (x86-64)	Linux (x86-64)	Linux (aarch64)
