Thanks for your compiling instructions! ^▽^

I have a new question, there's such a remark in /meshlab/src/README.md :

MeshLab has a plugin architecture and therefore all the plugins are compiled separately; some of them are harder to be compiled. Don't worry, if a plugin fails to compile just remove it and you lose just that functionality.

So generally, how to compile and run plugins like /meshlab/src/meshlabplugins/filter_screened_poisson separately?

Thanks for your time and attention!
