#### CMake:
CMake can build either a self-contained application bundle, which includes all the necessary game files and dependencies, or it can build a command line version that links against system installed dependencies. CMake will retrieve the dependencies from [Dependencies](https://github.com/OpenRCT2/Dependencies/) automatically. You can build the macOS app using CMake using the following commands:
```
mkdir build
cd build
cmake ..
make install
cmake -S . -B build
cmake --build build --target install
```
Then you can run the game by opening `OpenRCT2.app`
To build the command line version, you'll need to disable the macOS app bundle:
```
mkdir build
cd build
cmake .. -DMACOS_BUNDLE=off
make
cmake -S . -B build -DMACOS_BUNDLE=off
cmake --build build
cmake --build build --target install
ln -s ../data data
```
Then you can run the game by running `./openrct2`.

### Linux:
The standard CMake build procedure is to install the [required libraries](https://github.com/OpenRCT2/OpenRCT2#linux), then:
```
mkdir build
cd build
cmake ../ # set your standard cmake options, e.g. build type here - For example, -DCMAKE_BUILD_TYPE=RelWithDebInfo
make # you can parallelise your build job with e.g. -j8 or consider using ninja
DESTDIR=. make install # the install target creates all the necessary files in places we expect them
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=. # set your standard cmake options, e.g. build type here - For example, -DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build build # you can parallelise your build job with e.g. -j 8 or consider using ninja
cmake --build build --target install # the install target creates all the necessary files in places we expect them
```
You can also use Ninja in place of Make, if you prefer, see Wiki for details.
You can also use Ninja in place of Make using `-G Ninja` in the first command, if you prefer, see Wiki for details.
Detailed instructions can be found on [Building OpenRCT2 on Linux](https://github.com/OpenRCT2/OpenRCT2/wiki/Building-OpenRCT2-on-Linux).
Note: the `cmake -S . -B build` syntax is available for CMake >= 3.14. For older versions use:
```
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=. # set your standard cmake options, e.g. build type here - For example, -DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build . --target install
```
