* 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.

// This is SSE version of svd3x3 (see svd3x3.h) which works on 4 matrices at a time
|
|
// These four matrices are simply stacked in columns, the rest is the same as for svd3x3
|
|
//
|
|
// Inputs:
|
|
// A 12 by 3 stack of 3x3 matrices
|
|
// Outputs:
|
|
// U 12x3 left singular vectors stacked
|
|
// S 12x1 singular values stacked
|
|
// V 12x3 right singular vectors stacked
|
|
//
|
|
// Known bugs: this will not work correctly for double precision.
