I needed to specify DEPENDS = "protobuf-native" to get it working, I
would be really interested to understand exactly what that does, but I
must admit to myself I can't understand everything in a single shot.

So never mind.

I still have another question :-)

I am about to create another recipe for the gprc library for C++, to
build it on my local machine has been pretty simple:

$ git clone -b $(curl -L http://grpc.io/release)
https://github.com/grpc/grpc
$ cd grpc
$ git submodule update --init
$ make
$ [sudo] make install

The recipe I have created so far would clone/checkout the source code
from a GIT repo or something similar and then the build process could
start straight away.

In my case I have an additional step:

git submodule update --init

Is there a function/hook I can override in the recipe ?

Thanks,
P.
