Clipper

[shaolo1]

You mention in README.md
The library depends on zlib and qhull

There is also a dependency on Clipper (src/clipper_tools.cpp #include <clipper/clipper.hpp>) but it is not mentioned.

I got a good compile by using this fork.
https://github.com/brandon-kohn/clipper-lib

Is this the version you are using?

Is there any plan to move to Clipper2 (https://github.com/AngusJohnson/Clipper2) since the original clipper lib is quite old and the performance of the new version is quite impressive?

Thanks in advance!
