Hello,

I am trying to compile MeshLabJS in order to learn how Emscripten and WASM works in conjunction with ThreeJS, but following the documentation, it fails with an error in vcglib unable to initialize Inertia.

Here is the complete output on Linux:

It is the same output on Windows, sort of speak, as build.bat does not exist, so I am using the same make -f MakefileJS command.
