I figure out the gmock "unreference" error, I forget add the gmock lib in my project CMakeLists.txt:

change the following two line in my CMakeLists.txt

find_library(NAMES gtest)
target_link_libraries(${targetName} PRIVATE gtest) # link google test to this executable

into:

find_library(NAMES gtest gmock)
target_link_libraries(${targetName} PRIVATE gtest gmock) # link google test to this executable

then linking passed, but there is still the "duplicate" warings:

From the information provided, we think this is unlikely to be an issue on our side.

https://github.com/google/googletest/blob/master/docs/quickstart-cmake.md is our CMake quickstart tutorial.

If you still believe this is a problem on our side, please provide us with more information.

I'm going to convert this issue to a discussion so the community can help.

Thanks, I will refer to the quickstart-cmake guide and try again!
