I built a tensorflow lite micro library successfully.

".\Objects\TensorflowLiteMicro.lib" - 0 Error(s), 0 Warning(s).
So, I got a .lib file.
However, something happened when I imported the library to my project and compiled the whole project.
There are multiply defined errors between the library and another library in my project .
Compiling result In My project:

Not enough information to list image symbols. Not enough information to list load addresses in the image map. Finished: 2 information, 0 warning and 8 error messages.
How can I remove the redefined source files btod.o? I can't find them in my Tensorflow Lite Micro library project.
