Thanks for filing this bug, Helmut!

And sorry for overlooking at this. opentelemetry-cpp-dev currently
includes (part of) the proto header files, that were used to build the
-cpp header-only library. IIUC, if we had to remove one of those
packages, it would have to be libopentelemetry-proto-dev, in favor of
opentelemetry-cpp-dev. But, if openlemetry-proto (as the OTLP protocol
implementation in C++) happens to be needed as as dependency of any
other package, I would prefer to keep both packages.

My plan is to remove the /usr/include/opentelemetry/proto/ files from
opentelemetry-cpp-dev. Looking into tango (the main opentelemetry
reverse dependency), it only includes/need the header files from the C++
client library. I've actually tested building tango with a "clean"
opentelemetry-cpp-dev and it succeeds.
Thomas, please tell me if this doesn't make sense to you.

Unless there is any objection, I will upload a hopefully fixed
opentelemetry-cpp-dev in a couple of days.

Cheers,
