# Urho3DPlayer target is rather special, although it is here, it is not a tool because it is built into target platform binary as opposed to host platform
# In order to test the player on Web platform built using Emscripten, the request parameters need to be parsed into Module['argument'] (see https://github.com/kripken/emscripten/blob/master/src/emrun_prejs.js for inspiration)
# The CTest could "run" the Urho3DPlayer.html with script name as parameter, thanks to emrun performing this parsing automatically
# In a production environment, however, the request parameters parsing has to be done by the application itself one way or another
