tamasmeszaros 2ae2672ee9 Building igl statically and moving to the dep scripts
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.

// of the scalar field follows (new) edges of the output mesh. Effectively
// running "marching triangles" on mesh, but not in any coherent order. The
// output mesh should be as manifold as the input.
//
// Inputs:
// V #V by dim list of mesh vertex positions
// F #F by 3 list of mesh triangle indices into V
// S #V by 1 list of scalar field
// val value of S to remesh along
// Outputs:
// U #U by dim list of mesh vertex positions #U>=#V
// G #G by 3 list of mesh triangle indices into U, #G>=#F
// SU #U list of scalar field values over new mesh
// J #G list of indices into G revealing birth triangles
// BC #U by #V sparse matrix of barycentric coordinates so that U = BC*V
// L #G list of bools whether scalar field in triangle below or above val
