I managed to build llvm and clang and now I am trying to create a ClangTool according to clang docs. But I am getting the following error when I am trying to build i

You need to use keyword signature of target_link_libraries; effectively, you need to add PRIVATE to the target_link_libraries statement in your CMakeLists.txt:

target_link_libraries(loop-convert PRIVATE
  clangTooling
  clangBasic
  clangASTMatchers
)

This is because add_llvm_executable uses such signature and you can't mix them in CMake.
