projectM Emscripten Example
===========================
This application is a sample entry point for the emscripten-built version of projectM.
It's a very basic application without many features.
## Limitations
emscripten builds of projectM only support building as a static library. Shared libraries are only simulated and
basically identical to static libraries.
Multithreading and OpenMP support are disabled due to the lack of real multithreading capabilities in
JavaScript/WebAssembly.
The build will use OpenGL ES 3.0, using `FULL_ES2` compatibility only.
## Prepare for building
Download and build the emscripten SDK: https://emscripten.org/docs/getting_started/downloads.html
No other libraries are required as emscripten has everything built-in that is needed by projectM.
## Configure and compile projectM
CMake will auto-detect that emscripten is used for building as the toolchain sets `CMAKE_SYSTEM_NAME`
accordingly. No other options need to be set except `CMAKE_INSTALL_PREFIX` if you plan to install the build results for
further use.
Running these commands in projectM's source dir will configure and build projectM for Emscripten:
```sh
mkdir cmake-build-emscripten
cd cmake-build-emscripten
emcmake ..
emmake
```
If the build was successful, you will find the projectM_SDL_emscripten.html, .data, .js and .wasm files in
the `cmake-build-emscripten/src/projectM-emscripten`directory. The .data file includes all presets as a virtual
filesystem.
