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.

// ORTH Orthogonalization.
// ORTH(A,Q) produces Q as an orthonormal basis for the range of A.
// That is, Q'*Q = I, the columns of Q span the same space as
// the columns of A, and the number of columns of Q is the
// rank of A.
//
//
// The algorithm uses singular value decomposition, SVD, instead of orthogonal
// factorization, QR. This doubles the computation time, but
// provides more reliable and consistent rank determination.
// Closely follows MATLAB implementation in orth.m
//
// Inputs:
// A m by n matrix
// Outputs:
// Q m by n matrix with orthonormal columns spanning same column space as
// A
//
// Known bugs: Implementation listed as "Broken"
