Ubuntu - Right protobuf paths for ./configure comm

问题:

I am following Google official documentation for GAE (Google app engine) installation. Look at this part (relative to gae php extension): https://github.com/GoogleCloudPlatform/appengine-php-extension

./configure --enable-gae --with-protobuf_inc=<include_path> --with-protobuf_lib=<lib_path>

The documentation says:

Set <include_path> and <lib_path> to where you have installed the protobuf headers and libraries in the previous step.

I always get an error in the terminal when I run the ./configure command, because I don't know which are the right protobuf paths.

P.s.
When installing Protobuf I followed this documentation:
https://github.com/google/protobuf/blob/master/src/README.md

My /home/Experiments folder contains 3 folders:
php-src, appengine-php-extension, protobuf.
The protobuf folder is where I have "git cloned" protobuf to install it.

If you follow the instructions under Building in the linked repository for the App Engine PHP Runtime, you'll find that in step 2, you choose an output directory when generating C++ source and header files for remote_api.proto and urlfetch_service.proto. That folder would be the correct one to supply via cmd args.
