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.

// The algorithm iterates between projecting each quad to its closest planar

|
// counterpart and stitching those quads together via a least squares
|
|
// optimization. It stops whenever all quads' non-planarity is less than a

// is reached.
