* To setup your build enviroment and library dependecies, run the following commands:
2324
* Ubuntu (Mint, Pop!_OS, etc...): `sudo apt install build-essential git libsdl2-dev libvorbis-dev libogg-dev libtheora-dev`

* The `CXXFLAGS` option can be removed if you do not want optimizations.

* -j switch is optional, but will make building faster by running it parallel on multiple cores (8 cores would be -j9.)

33+
### CMake
34+
* Install the following dependencies depending on your platform through your terminal:
35+
* **pacman (Arch):** `sudo pacman -S base-devel cmake sdl2 libogg libtheora libvorbis`
36+
* **apt (Debian/Ubuntu):** `sudo apt install build-essential cmake libsdl2-dev libogg-dev libtheora-dev libvorbis-dev`
37+
* **rpm (Fedora):** `sudo dnf install make gcc cmake sdl2-devel libogg-devel libtheora-devel libvorbis-devel zlib-devel`
38+
* **apk (Alpine/PostmarketOS)** `sudo apk add build-base cmake sdl2-dev libogg-dev libtheora-dev libvorbis-dev`
39+
* Your favorite package manager here, [make a pull request](https://github.com/RSDKModding/RSDKv2-Decompilation/fork)
40+
41+
42+
* Then just run the following in the root repository directory:
43+
```
44+
cmake -B build
45+
cmake --build build --config release
46+
```
