OTLP exporter v1.22.0 - Resulting deployment is not correct

Describe your environment

RH 8.10

Installed everything from source for OTLP sdk/exporters only

For otel build

cmake -DCMAKE_INSTALL_PREFIX=/home/gp/usr/local/otel ..

Build & deployment succeeds.

What is the expected behavior?

"make install" will deploy all needed artefacts.

Setting the below in my CMakeList.txt to be sufficient

list(APPEND CMAKE_PREFIX_PATH "/home/gp/usr/local/otel/lib64/cmake/")
find_package(opentelemetry-cpp CONFIG REQUIRED)

What is the actual behavior?

CMake fails, it tries to find libraries I thought are only needed for the SDK building

-- find_required_dependencies: calling find_dependency(Protobuf CONFIG )...

CMake Error at /usr/share/cmake/Modules/CMakeFindDependencyMacro.cmake:76 (find_package):
Could not find a package configuration file provided by "Protobuf" with any
of the following names:

ProtobufConfig.cmake
protobuf-config.cmake

Add the installation prefix of "Protobuf" to CMAKE_PREFIX_PATH or set
"Protobuf_DIR" to a directory containing one of the above files. If
"Protobuf" provides a separate development package or SDK, be sure it has
been installed.

Have I done something wrong or my expectation, the OTEL public API doesnt pull any third party dependency, is wrong?

Reproduce the installation using install/cmake/third_party_latest and the CMakeLists.txt configuration shown, then inspect the installed opentelemetry-cpp CMake package configuration. Start with the generated dependency declarations and the failing find_package(Protobuf CONFIG) call. Done means determining whether make install provides or correctly documents every dependency needed by the requested OTLP components.
