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.

// PIECEWISE_CONSTANT_WINDING_NUMBER Determine if a given mesh induces a
|
|
// piecewise constant winding number field: Is this mesh valid input to solid
|
|
// set operations. **Assumes** that `(V,F)` contains no self-intersections
|
|
// (including degeneracies and co-incidences). If there are co-planar and
|
|
// co-incident vertex placements, a mesh could _fail_ this combinatorial test
|
|
// but still induce a piecewise-constant winding number _geometrically_. For
|
|
// example, consider a hemisphere with boundary and then pinch the boundary
|
|
// "shut" along a line segment. The **_bullet-proof_** check is to first
|
|
// resolve all self-intersections in `(V,F) -> (SV,SF)` (i.e. what the
|
|
// `igl::copyleft::cgal::piecewise_constant_winding_number` overload does).

|
// Inputs:
|
|
// F #F by 3 list of triangle indices into some (abstract) list of
|
|
// vertices V
|
|
// uE #uE by 2 list of unique edges indices into V
|
|
// uE2E #uE list of lists of indices into directed edges (#F * 3)

// Returns true if the mesh _combinatorially_ induces a piecewise constant
|
|
// winding number field.
