For meson, I can even add a required version.

What about
ninja -C build?

Done.

| This will produce a `lib/compiled.js` exporting the classes defined in C++ code. | 
| ### Technical details | 
| Compilation is currently a two-step process. In the bindings generation step, | 
| the source files are compiled into `compiled/bindings.cpp.js` with the | 
| `PRINT_BINDINGS` symbol defined. This application is then executed via Node.js | 
| and will print JavaScript wrappers for the C++ classes to | 
| -`compiled/bindings.js` according to definitions within the `EMSCRIPTEN_BINDINGS` | 
| +`build/bindings.js` according to definitions within the `EMSCRIPTEN_BINDINGS` | 
| macro in `compiled/bindings.cpp`. | 
| In the actual compilation step the source files are compiled into | 
| `lib/compiled.js` without the `PRINT_BINDINGS` symbol, so that the | 
| `EMSCRIPTEN_BINDINGS` macro ignores its contents and merely emits some generic | 
| functions necessary for the JavaScript bindings to work. The previously | 
| generated `compiled/bindings.js` file is added to the end of Emscripten output. |
