      Description

      Trying to build qttools from the dev branch fails with a load of unresolved LLVM and clang symbols when linking lupdate.

      It is missing the following libraries:
      LLVMSupport clangBasic clangTooling clangAST clangFrontend clangLex clang-cpp

      I'm attaching a workaround patch, but chances are WarpLibClang::WrapLibClang needs to be fixed to detect the needed libraries instead.

      Build output without the patch:
