Error while building simple pub/sub project from examples

[nullbyto]

Describe the bug

Hello, I am new to Zenoh, I am trying to build a simple publisher/subscriber program (taken from docs: https://zenoh-cpp.readthedocs.io/en/latest/pubsub.html) for testing, when building i get this error:

gmake: *** [Makefile:111: all] Error 2

I get the same error while trying to build the zenoh-cpp examples.

To reproduce

After i built zenoh-c and zenoh-cpp.

In test project with publisher.cpp and subscriber.cpp, I do:

mkdir -p build && cd build
cmake ..
make

I get the error after running make.

CMakeLists.txt:

project(test-zenoh)

cmake_minimum_required(VERSION 3.16)

if(CMAKE_BUILD_TYPE STREQUAL "")
    set(CMAKE_BUILD_TYPE Release)
endif()

find_package(zenohc REQUIRED)
find_package(zenohcxx REQUIRED)

# for both publisher and subscriber
add_executable(pubs publisher.cpp)
add_executable(subs subscriber.cpp)

target_link_libraries(pubs PUBLIC
    zenohcxx::zenohc
)
target_link_libraries(subs PUBLIC
    zenohcxx::zenohc
)
set_property(TARGET pubs PROPERTY LANGUAGE CXX)
set_property(TARGET pubs PROPERTY CXX_STANDARD 17)
set_property(TARGET subs PROPERTY LANGUAGE CXX)
set_property(TARGET subs PROPERTY CXX_STANDARD 17)

Hello, sorry there is a small lag between updating zenoh-c and zenoh-cpp versions, #241 should resolve it.
