[CMake] Using CMake to build an Emscripten output?

[Jean-Christophe Fillion-Robin]

Hi Eric,

While I don't have yet an example dealing with assets, here is an example
of project using emscripten. See https://github.com/commontk/dcmjs

May be you could re-use the macro "em_add_tracked_link_flag" like it is
done for --pre-js, etc .... See [1]
