- Protobuf Version : 4.22.2
- CMake Version : 3.27.0
- C++ Complier version : MSVC 19.36.32537.0
- My English is poor, so I hope you will be patient to read it, please.
- I compile protobuf to static library and link it to my project, but always come out this error:
- this is my project main CMakeLists.txt code :

- If anyone can help me, thank you very much!!
I have tried link the absl libraries and add Release Build Type but it still comes out this error.
