* 1. Remove all global include_directories.
* 2. Move 3d party dependencies from src to budled deps if possible.
* Unify and enforce one way of including headers:
e.g. #include "libslic3r/GCode.hpp" vs #include "GCode.hpp"
(always use the "libslic3r/GCode.hpp" option).
* Make all dependencies (also header only) a cmake target.

// Exact geodesic algorithm for triangular mesh with the implementation from https://code.google.com/archive/p/geodesic/,
|
|
// and the algorithm first described by Mitchell, Mount and Papadimitriou in 1987
|
|
//
|
|
// Inputs:
|
|
// V #V by 3 list of 3D vertex positions
|
|
// F #F by 3 list of mesh faces
|
|
// VS #VS by 1 vector specifying indices of source vertices
|
|
// FS #FS by 1 vector specifying indices of source faces
|
|
// VT #VT by 1 vector specifying indices of target vertices
|
|
// FT #FT by 1 vector specifying indices of target faces
|
|
// Output:
|
|
// D #VT+#FT by 1 vector of geodesic distances of each target w.r.t. the nearest one in the source set
|
|
//
|
|
// Note:
|
|
// Specifying a face as target/source means its center.
