libclingJupyter.so didn't created using build instructions

After using these commands, cling works as expected.

git clone https://github.com/root-project/llvm-project.git
cd llvm-project
git checkout cling-latest
cd ..
git clone https://github.com/root-project/cling.git
mkdir cling-build && cd cling-build
cmake -DLLVM_EXTERNAL_PROJECTS=cling -DLLVM_EXTERNAL_CLING_SOURCE_DIR=../cling/ -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_TARGETS_TO_BUILD="host;NVPTX" -DCMAKE_BUILD_TYPE=Release ../llvm-project/llvm
cmake --build . --target clang
cmake --build . --target cling

However when I run these instructions for Jupyter support

export PATH=/cling-install-prefix/bin:$PATH
cd /cling-install-prefix/share/cling/Jupyter/kernel

pip install -e .
jupyter-kernelspec install --user cling-cpp17
jupyter-kernelspec install --user cling-cpp1z
jupyter-kernelspec install --user cling-cpp14
jupyter-kernelspec install --user cling-cpp11

I got kernel inside Jupyter but it dies immediately. As far as i understood, the earlier issues solved with an update and there is no similar problems. Here is the error:

    raise RuntimeError('Cannot find ' + clingInstDir + '/lib/libclingJupyter.{so,dylib,dll}')
RuntimeError: Cannot find /home/xxx/Documents/projects/cling/cling-build/lib/libclingJupyter.{so,dylib,dll}

It seemes like the file doesn't even created in .../cling-build/lib/. So, I don't think it's about not finding the file. When I ran make command inside .../cling-build/tools/cling/tools/Jupyter, it solved the issue. Now, I have .../cling-build/lib/libclingJupyter.so and works fine.

I didn't get any error while linking and my consecutive runs didn't changed anything. Maybe important point, I learnt that I need to run first after my first error cmake --build . --target clang. However, I also ran cmake --build . --target cling afterwards so I don't think this is the issue.

I'm on fedora 40 and ran soft linked directory from another drive if it helps.
