   Of course, i believe you will need to first compile pulsar from source ( i found same issue with brew libpulsar ) then create a new c/c++ project with a CMake that will need to first find the pulsar lib then try to compile your library ( without including curl into your Cmake) So this is all a little bit of a setup to re-produce but i can help as much as i can. The CMake i have is fairly tied to our project but maybe give you some sort of overview on how we set it up ...
   
   We have pulsar cloned into a `external` package. We compile pulsar like so ... 
   ```
   OUT_DIR="${BASE_DIR}/compiled"
   SRC_DIR="${BASE_DIR}/pulsar/pulsar-client-cpp"
   BUILD_DIR="${SRC_DIR}/pulsar-dist"
   rm -r ${BUILD_DIR} || true # could fail
   mkdir ${BUILD_DIR} || exit
   #echo "Made $BUILD_DIR"
   cd ${BUILD_DIR} && cmake -DBUILD_TESTS=OFF \
         -DBUILD_PYTHON_WRAPPER=OFF \
         -DCMAKE_INSTALL_PREFIX="${OUT_DIR}" \
         ${SRC_DIR}
   
   # build
   cd ${BUILD_DIR} && make -j 16
   
   cd ${BUILD_DIR} && make install
   ```
   
   We will have a `compile/include/pulsar` and a `compiled/lib` where `compiled/lib` contains all of the `libpulsar.a` related files. 
   
   Now we go into my project home, create our `_out` directory and run `cmake ../.`
   
   The CMake will find that pulsar lib, link libraries, and create our executable. 
   
   Once Cmake does its thing we run `make -j8`. After our sources compile, the linker commands will fail for our executable for pulsar like the errors I posted above. 
   
   The only solution i was able to figure out was linking curl into my target libraries. 
   
   I hope this can help in some way...
