To follow up on Antony's points,

Blender's solidify modifier is fine for a quick results but doesn't
re-mesh the shell which limits its use.
So the option to use a higher quality shell calculation method is welcome.

As for the dependencies, we already bundle Eigen.
libigl repository contains many external-libraries, however they don't
have to be committed into our source tree since its a header only
To review for inclusion, it comes down to which headers your work depends on.
