# You may find that on your travis CI or on the master branch that for some reason travis is timing out,
# ccache can fix this if you compile the dependency manager one at a time since VTK takes 50 minutes to compile on travis
# To do this, go into the superbuild cmake and simply comment out the packages so that opencv only builds, then vtk and opencv, etc
# After that, also make sure the script terminates afterwards immediately so travis can pack and upload the cache
