# raylib CMake Project
|
||||
|
||||
This provides a base project template which builds with [CMake](https://cmake.org).
|
||||
|
||||
## Usage
|
||||
|
||||
To compile the example, use one of the following dependending on your build target...
|
||||
|
||||
### Desktop
|
||||
|
||||
Use the following to build for desktop:
|
||||
|
||||
``` bash
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
|
||||
### Web
|
||||
|
||||
Compiling for the web requires the [Emscripten SDK](https://emscripten.org/docs/getting_started/downloads.html):
|
||||
|
||||
``` bash
|
||||
mkdir build
|
||||
cd build
|
||||
emcmake cmake .. -DPLATFORM=Web -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXE_LINKER_FLAGS="-s USE_GLFW=3" -DCMAKE_EXECUTABLE_SUFFIX=".html"
|
||||
emmake make
|
||||
```
