@wentasah
Thank you for your contribution !
As I do not directly use that part of the pointcloud preprocessor, I will ask the author of that part

@beginningfan
It seems you added this dependency (#924).
Do you have an opinion about MPFR?
Unless it is actually used, it would just increase the size of the container, etc

I forgot to mention that the build fails without any of these added packages. If MPFR is not available, configure fails with:
