You asked on IRC if it's possible to have only one openpowerlink package.
I would say yes, by adding a top-level CMakeLists.txt like this one [1] but
the build dependencies between each projects are not handled.
All is build at the same time.
This is a problem for demo applications which are looking for openpowerlink
libraries using FIND_OPLK_LIBRARY, but before it had time to be compiled.

I don't know how to add a dependency between the "stack" project and the "app"
project.

Otherwise, we need to package each sub projects in order to handle the
dependency outside of the CMake world...

Samuel, have you an idea ?

Best regards,
Romain
