I am trying to build ns3gym following the instructions in the README. I have installed all the required packages, but I get the error message "-- protobuf_generate command not found -> use a local copy from /home/sgxcy1/ns-3-dev/contrib/opengym/protobuf-generate.cmake", after I run "./ns3 build". There are additional error messages printed out at the end of the building process, which I think is caused by the aforementioned error. The messages are as follows:
"
CMake Error at scratch/CMakeLists.txt:47 (add_executable):
Target "scratch_scratch-simulator" links to target "protobuf::libprotobuf"
but the target was not found. Perhaps a find_package() call is missing for
an IMPORTED target, or an ALIAS target is missing?
Call Stack (most recent call first):
scratch/CMakeLists.txt:67 (create_scratch)

In case it matters, I am using Ubuntu 22.04 on Windows Subsystem for Linux. The protoc and cmake versions are as follows:
"
sgxcy1@DESKTOP-R887JOJ:~/ns-3-dev$ cmake --version
cmake version 3.22.1
CMake suite maintained and supported by Kitware (kitware.com/cmake).
sgxcy1@DESKTOP-R887JOJ:~/ns-3-dev$ protoc --version
libprotoc 3.12.4
"
I wonder how to solve this problem urgently. I am stuck here for days. Thanks for any reply and potential solutions.
