upstream switched buildsystem to cmake, yay!
test version is at layman -a xmw, but I need to check compatiility with openscad.
in the meanwhile where is sci-libs/opencascade-7.1 and vtk-7.1 but in portage its still not update. older version is not anynore available free to download. so please update to sci-libs/opencascade-7.1 and let it use upto date vtk-7.x. thanks
