OK I solve this problem, it is really stupid. It is caused by my unfamiliarity
of clion ide.
When I'm using Clion IDE, It will set up a doc called "/cmake-build-debug".
It's like our file "/build".
However , it lack of the file "config.cmake"
I guess it is my CLION IDE cmake-debug goes wrong?
It does not shows that llvm has been found!
when I use Ctest build/cpptest in terminal, it is totally ok! no bug, it proves
that is caused by IDE cmake-d
I want to confirm that I make my LLVM support indeed, so I add a random string
in src/target/llvm/llvm_module.cc, and remake TVM, it shows that I do compile
with this llvm_module.cc file.
pay attention to my compliation process. It recompile llvm_module.cc
How can I fix it?
My LLVM system path is quiet correct, and I do make config.cmake as tutorial.

It does mean that the LLVM is not enabled. The particular global function
"target.build.llvm" is defined in the file "src/target/llvm/llvm_module.cc".
Would you like to check if this file is included?

I find that when I create this PackedFunc* object, I can't find
"target.build.llvm"
**this Manager* m has not "target.build.llvm" attrs inside!**
