issues with building demo example

[SimonDev666]

Hello vgvassilev,

Op Sys: Kali Linux v2024.3 (updated + upgraded)
cling: most current version (as per build script below)
level of experience with cmake / cling: low+

we were talking on the cppyy github site about issues i was having with building cling into a standalone solution, then embedding within my qt c++ solution. i that conversation you suggested i use the 'demo' example in 'tools'. i tried this but still no luck.

Here is my build script:
"
mkdir experimental
cd experimental
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 cling
cmake --build . --target clang
"

as per your web page in github for the 'demo' example, i tried the following:
"
cmake -Dcling_DIR=/home/simon/Experimental/cling-build/lib/cmake/clang /home/simon/Experimental/cling/tools/demo
"

i noticed there is no cling-build/lib/cmake/clang directory created after the build process.
i also get the following errors:
"
CMake Error at CMakeLists.txt:25 (find_package):
By not providing "Findcling.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "cling", but
CMake did not find one.

Could not find a package configuration file provided by "cling" with any of
the following names:

clingConfig.cmake
cling-config.cmake
Add the installation prefix of "cling" to CMAKE_PREFIX_PATH or set
"cling_DIR" to a directory containing one of the above files. If "cling"
provides a separate development package or SDK, be sure it has been
installed.
"

i checked and there is no files for "cling*.cmake" anywhere in Experiemental (in any of the 3 directories within it - cling, cling-build, llvm-project)

is there any chance in helping me solve this issue and what i am doing wrong - please.
