Fixing dep build script on Windows and removing some warnings. Use bundled igl by default. Not building with the dependency scripts if not explicitly stated. This way, it will stay in Fix the libigl patch to include C source files in header only mode.

// 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.
