Work with conda-forge packages.
The following environment may be sufficient.

- conan 
- ninja
# - vcpkg

# https://github.com/conda-forge/clangdev-feedstock
- clang

# - clang-format-16
- clang-tools
- clangdev
# - clangxx

# - libclang13
# - python-clang

# https://github.com/conda-forge/llvmdev-feedstock
- libllvm16
- lit
- llvm
- llvm-tools

As it is conda it should work for any platform.

I am working on a PR.
