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.

// incident on corner c of face f. In contrast, edge_flaps's EMAP(f,c)

// reveals the edge _opposite_ corner c of face f
