A pre-release example: 0.4.9-nightly.2017.1.17+commit.6ecb4aa3.Emscripten.clang Important Information About Versioning ¶ After a release is made, the patch version level is bumped, because we assume that only patch level changes follow. Otherwise if the library uses CMake, we’ll similarly use Emscripten’s CMake wrapper, named emcmake: emcmake cmake -DCMAKE_INSTALL_PREFIX="$(pwd)/install" Note: We set the prefix for an in-tree install to prevent us from accidentally deploying WebAssembly binaries to our default system path.

Unit Testing Emscripten Library in Browser Using CMake and Nightwatch.JS. This makes it possible to actually use CMake's own target_*_options functions, e.g. Emscripten is intelligent enough to redirect our output to console.log so we don’t need to do anything else . /edit For the sake of completeness: Emscripten now allows to remove the whitespace between the -s prefix and the actual flag.

However, you can optionally set the EMSCRIPTEN_SYSROOT environment variable or build option to point to another system root path. The other two are just an example class for a script controlling a sprite. OpenGL CMake Skeleton . Build ignition libraries with emscripten (WIP).
