Not all submodules are available after clone or updated when issuing 'submodule update' on a cleanly cloned source tree
vtkprotobuf submodule is not available after git clone --recursive
nor is updated after submodule update
. Only after running Utilities/SetupForDevelopment.sh
is it available. It looks like there are more submodules that are only initialized by the SetupForDevelopment.sh script.
Can this be tuned, such that a git clone --recursive
creates a valid source tree?
